Find the Security Risk in Your Applications, Fix It, and Prove Each Item Is Closed
GullySystem assesses web, mobile, API and cloud systems for Indian businesses — testing authentication, permissions, code and configuration, then delivering ranked findings with evidence, a remediation plan, fix support and a retest that confirms each item is closed.
- Scope and rules of engagement agreed in writing before any testing
- Findings ranked by business impact, with evidence you can reproduce
- Fix support and a retest that shows which items are actually closed
We review the systems Indian businesses put in front of customers and staff: dealer and customer portals, clinic and diagnostic systems holding patient records, school and coaching platforms with parent logins, logistics tracking APIs, payment and document flows, and cloud accounts that grew one server at a time. Some of this work is a review before a launch. Some of it is triggered by an enterprise customer’s security questionnaire, and some by an application inherited from a vendor who is no longer contactable.
Do You Know What Someone Outside Your Company Can Reach Inside Your Application?
A Customer Saw Somebody Else’s Data
A user changed a number in the address bar, or opened an old link, and another customer’s invoice, report or document appeared. You found out from a complaint rather than from a check. The technical fix is often small; the phone call, the loss of trust and the question of who else did the same thing are not.
Everyone Has Full Access Because It Was Quicker That Way
Logins were created as people joined and never narrowed. The accounts assistant can delete records, a field executive can export the full customer list, and two people who left last year still have working credentials. Nobody has looked at the list since the software went live.
Files Sitting Where Anyone With the Link Can Open Them
KYC documents, signed contracts, patient reports or database backups live in a cloud folder or a shared drive that was opened up once for convenience. There is no login in front of them, no expiry on the link, and no record of who has already downloaded them.
Security Only Comes Up When a Customer’s Auditor Asks
A large client or a bank sends a security questionnaire before signing, and the deal stops while your team tries to answer questions about encryption, access reviews and testing that nobody has ever documented. Weeks of sales momentum are lost to a form.
A Scan Report Nobody Could Act On
Someone ran a tool and handed over hundreds of items with no order of importance. Your developer says half are false alarms, the rest have no clear owner, and the file has been sitting in a folder for months. You paid for a report and your risk did not change.
Passwords and Keys Passed Around in Chat
Database passwords, payment gateway keys and server logins are in a WhatsApp group, an email thread or a shared sheet. Some were shared with a vendor who no longer works with you. Nothing was rotated when people left, and no one could say today which key is used by which system.
Things Left Running on the Internet That No One Owns
An old admin panel, a test copy of the site, a forgotten server or a database port is still reachable from outside, usually from a project finished years ago. It gets no updates and no attention, and it is exactly what an automated attack finds first.
You cannot fix what nobody has looked at, and you should not have to fix everything at once. What you need first is an honest picture of what is exposed, ordered by what it would actually cost your business.
A Clear Picture of Your Risk, in Business Language, With the Fixes Done
We test your applications, APIs, cloud accounts and access controls the way somebody trying to misuse them would, then write up what we found with evidence, rank it by what it would cost you, help your team fix it, and retest so closure is a matter of record rather than an assurance.
Tested by Hand, Not Only by a Tool
Scanners catch known patterns. The findings that hurt — one user reaching another user’s records, a discount or a limit changed on the way to the server, a role doing more than it should — are found by a person working through your actual screens and roles.
Ranked by What It Would Cost You
Each finding is written twice: what the technical issue is, for your developer, and what it would mean for your customers, money or obligations, for you. That is what decides the order of work instead of the colour of a severity label.
Fixed and Retested, Not Just Reported
We stay through remediation — advising your developers or making the changes ourselves — and then retest the specific findings, so you hold evidence of what was closed and a written note of anything you consciously chose to accept.
What Changes After a Security Review
Focus on business value before discussing technology. Here is what your team accomplishes in week one.
A Risk List You Can Actually Work Through
One register, ordered by business impact, with an owner and a next action against every item, instead of a raw tool export that no one opens twice.
People See Only What Their Job Needs
Roles, permissions and admin rights reviewed and tightened, ex-staff and ex-vendor accounts removed, and a way to check the list again every quarter.
Findings Fixed and Verified
High and medium items corrected and then retested against the original evidence, so closure is proven rather than assumed from a developer’s message.
Answers Ready for Customer Questionnaires
A dated report, a remediation record and a retest result you can put in front of an enterprise client, a bank or an auditor when they ask what you have tested.
Exposure Found Under Agreed Rules, Not by a Stranger
A weakness in a new portal or app is found inside a test window you approved, by people you engaged, instead of by an outsider scanning the internet or a user who then tells everybody.
Security Checks That Keep Running
Dependency, secret and configuration checks added to your build pipeline so new code is checked as it ships, not once a year before an audit.
What Cybersecurity and Application Security Includes
Everything required from operational discovery to production deployment and long-term maintenance.
Security Consulting and Risk Review
A working session on what your business holds, who touches it and where the real exposure sits, ending in a plan you can budget for rather than a generic checklist.
Web Application Security Assessment
Testing of your portal, dashboard or website across login, sessions, roles, payments, forms, uploads and reports, using real user journeys and every role your system defines.
Mobile Application Security Assessment
Android and iOS builds examined for data stored on the device, traffic that can be intercepted, keys shipped inside the app, and screens or actions reachable outside the intended flow.
API Security Testing
Your APIs tested directly — authentication, token handling, record-level permissions, mass data pulls, rate limits and error responses — because the app screen is not the only way in.
Vulnerability Assessment and Penetration Testing
A structured VAPT combining automated coverage with manual exploitation attempts inside an agreed scope, delivered as findings with reproduction steps and evidence.
Secure Code Review
A read through the code that handles authentication, permissions, payments, uploads and queries, catching issues that never surface from the outside until the wrong input arrives.
Authentication and Permission Audit
Every role, admin account and integration user listed and compared against what that job needs, with password, multi-factor and session policies reviewed alongside.
Cloud and Server Security Review
AWS, Azure, Google Cloud or your own servers checked for open ports and storage, over-permissive roles and keys, missing patches, unencrypted volumes and backups nobody has tested.
Database and Data-Store Security
Who can reach the database and from where, how credentials are held, what is encrypted, how backups are protected, and whether sensitive fields can be masked for staff who only need to read.
Secrets, Keys and Credential Handling
Keys pulled out of code, chats and shared sheets into a controlled store, scoped to the minimum permission, with a rotation process for the day someone leaves.
Security Checks in Your Delivery Pipeline
Dependency, secret and configuration scanning wired into your build and release process so a new library or a stray key is caught while the change is still being made.
Monitoring and Incident-Response Support
Logging and alerting set up so unusual logins, mass downloads and privilege changes raise a flag, plus a written plan and our support for the day something does go wrong.
Data-Privacy and Standards Readiness
A review of what personal data you collect, where it goes and how long you keep it, and the technical work that supports an ISO 27001, SOC 2 or DPDP effort your auditor will assess.
Where a Security Review Earns Its Cost
Real-world business processes we configure and automate.
Distributor: Dealer Pricing That Must Not Cross Between Logins
A distributor is about to open a portal where dealers see their own rates, credit limits and order history. A pre-launch review checks that one dealer cannot reach another dealer’s pricing by editing an ID, that discounts cannot be altered between the browser and the server, and that the login handles shared devices at the counter, so the commercial terms that took years to negotiate are not visible across the network on day one.
Diagnostics Chain: Patient Reports Reachable by Link
A diagnostics chain sends report links by SMS and WhatsApp. Testing shows the link works without a login, never expires and follows a guessable pattern, which puts other patients’ reports within reach. We rework the download to require a verified identifier, expire links, log every access, and review how long reports and identity documents are kept.
Manufacturer: Cloud Hardening After Migration
A manufacturer moves its ERP and shop-floor dashboards to the cloud, and the fastest route was open access rules, one shared administrator key and a database reachable from the internet. A configuration review closes the exposure, splits access by role, moves keys into a proper store and turns on backups and alerts, without disturbing the plant’s working hours.
Coaching Institute: Parent and Student Logins
A coaching institute runs a platform with student marks, attendance and parent contact numbers, and every staff member logs in as an administrator. The audit replaces that with role-based access, removes accounts of teachers who have left, adds multi-factor for administrators, and stops a student account from viewing another batch’s records.
Logistics Operator: One API Key Held by Every Customer
A transport operator gives customers an API to track consignments, secured by a single key shared across all of them. Testing shows one customer can query another’s consignment numbers and pull the full list. We move to per-customer credentials with record-level checks and rate limits, so a shared key is no longer a window into the whole book.
Professional Firm: Nobody Can Say Who Still Holds the Keys
An advisory firm takes over a client portal from a developer who has stopped responding. Nobody knows what is exposed, what the old admin panel does, or who still holds the keys. A takeover review inventories what is running, closes the forgotten staging site, rotates every credential and produces a prioritised list before any new work starts.
Is This Service Right for Your Business?
We partner with established businesses that have outgrown manual processes and want reliable systems.
Businesses About to Launch a Customer-Facing Application
Companies opening a portal, app or online store where customers, dealers or patients will log in and see records belonging only to them, and who would rather find the access problems before their users do.
Companies Holding Personal or Financial Data
Clinics, laboratories, schools, lenders, insurance intermediaries and service firms holding identity documents, health records, marks, contracts or payment details on behalf of other people.
Suppliers Being Asked Security Questions by Their Customers
Businesses whose enterprise clients, banks or partners now send a security questionnaire before onboarding, and who need real testing and documentation rather than a hopeful answer.
Teams That Have Just Moved to the Cloud
Organisations whose servers, storage and databases were migrated quickly under a deadline, with access rules left open so the migration could finish on time.
Owners Who Have Inherited Software From Another Vendor
Companies running an application built by a developer who is no longer available, where nobody can say what is exposed, which credentials are still live, or what the old admin screens can do.
When a Full Assessment Is Not Your First Step
If your application changes every week and is not yet in front of real users, wait until the build settles — a report on code that is about to be rewritten is wasted money. If you have never done the basics, do them first: turn on multi-factor authentication, remove accounts of people who have left, stop sharing one admin login, and check that your backups restore. Those cost nothing and remove more risk than an assessment will. A simple brochure website with no login and no customer data rarely needs a full VAPT, and we will tell you so.
Enterprise Capabilities in Plain Business Terms
Authentication and Session Testing
Login, password reset, OTP flows, session expiry and multi-factor behaviour tested for ways in that skip the intended path.
Record-Level Access Checks
Systematic attempts to reach another user’s order, invoice, report or document by changing identifiers, the failure behind most real-world data leaks.
Input and Injection Testing
Forms, search boxes, filters and API fields probed for injection, script execution and logic that can be bent by unexpected input.
File Upload and Document Access
What can be uploaded, where it is stored, whether it can be executed, and whether a document URL works for someone who is not logged in.
API Keys, Tokens and Rate Limits
Token issue and expiry, permission scope, replay of old tokens, and whether bulk extraction is throttled or wide open.
Mobile Storage and Traffic Review
Data left on the device, keys shipped in the build, certificate handling and whether traffic can be read or altered in transit.
Cloud Configuration Review
Storage exposure, network rules, over-broad roles, unused keys, encryption settings and logging across your cloud account.
Server and Network Exposure Mapping
A list of what is actually reachable from outside your office, including forgotten test sites, admin panels and open database ports.
Database Access and Encryption
Connection permissions, credential handling, encryption at rest and in transit, backup protection and masking for sensitive fields.
Secret and Credential Scanning
Repositories, configuration files and pipelines checked for keys and passwords committed by mistake, with a rotation plan for anything found.
Logging and Alerting Review
Whether an unusual login, a mass download or a privilege change leaves a trace, reaches a person, and can be reconstructed afterwards.
Retest and Closure Evidence
Each fixed finding re-run against the original steps, with the result recorded so closure can be shown, not stated.
Our Structured 6-Step Delivery Process
A transparent path from your first conversation to a reliable production release.
Scoping and Rules of Engagement
We agree exactly what is in scope and what is not, what kind of testing is allowed, and when it happens. From you we need the list of applications, URLs, APIs and cloud accounts to be covered, written authorisation from whoever owns each of them, a test window that suits your business hours, and one escalation contact reachable during testing.
Access, Test Accounts and Environment Setup
We decide whether to work on a staging copy or a live system with limits, and how each system will be reached. You provide a test account for every role in the application, a staging environment or a recent copy where one exists, read-only reviewer access to the cloud console, and any approval your hosting provider requires. Source code and repository access are needed only where a code review is in scope.
Assessment and Manual Testing
We map what is reachable, run tooling for coverage, then work through the application by hand across each role — authentication, permissions, data access, payments, uploads, APIs and configuration. Anything that could disturb live data or customers is confirmed with your contact before it is attempted, and we keep a log of what was tested and when.
Findings, Severity and Business Impact
You receive a findings register: what was found, the evidence, the steps to reproduce it, a severity, and a plain explanation of what it means for your customers, your money or your obligations. We walk your team through it in one session. From you we need a person who can decide priority and, where you choose to accept an item rather than fix it, put that decision on record.
Remediation Planning and Fix Support
Each item gets an owner, an approach and a sequence, so the highest-risk work is done first. Your developers can make the changes with our guidance and review, or we make them ourselves where you prefer. What we need from you is developer time held aside, or a clear handover of the code and environments if the fixing is ours.
Retest, Evidence and Ongoing Checks
We retest the fixed findings against the original steps and issue a retest report showing what is closed, what remains and what was accepted. We then hand over the security baseline, train the people who will watch the alerts and manage access, and set up periodic reviews or pipeline checks. For this we need a change window and a named person to own the baseline after we step back.

Why Business Owners Choose GullySystem
A Person Tests Your Application, Not Only a Scanner
Automated coverage is the starting point. The findings that matter to an SMB — one customer reaching another’s records, a role doing more than it should, a value changed on its way to the server — come from working through your screens by hand.
Every Finding Written for Two Readers
The technical description your developer needs, and the business consequence you need, side by side. That is what lets an owner decide what to fix this month and what can wait.
We Can Fix What We Find
We build software as well as review it, so remediation does not stop at advice. Where your team makes the changes, we review them; where you prefer, we make them ourselves and hand the code back.
The Retest Is Part of the Job
A report is only half the work. Fixed items are re-run against the original evidence and closure is recorded, so you hold proof rather than an assurance in an email.
Testing Planned Around Your Business, Not Ours
Scope, timing and intensity are agreed in writing. We prefer a staging copy, we throttle work on live systems, and anything that could disturb real data or customers is confirmed with your contact before it happens.
Honest About What an Assessment Proves
No assessment can promise an application has no vulnerabilities, and anybody who says otherwise is selling something. We tell you what was tested, what was not, and what the residual risk looks like.
Flexible Engagement Options
Choose an engagement model that matches your operational scope, budget, and timeline.
Pre-Launch Security Review
A focused assessment of a new application, portal or app before go-live, timed so the findings can be fixed inside the launch plan rather than after it.
Fixed-Scope Assessment
A one-time VAPT of an agreed set of applications, APIs and cloud accounts, priced against the scope document and delivered as a findings register with a remediation plan.
Assess, Fix and Retest
The assessment plus the remediation work and the retest as a single engagement, for teams without developer capacity to act on a report on their own.
Ongoing Security Support
Periodic reassessment, access reviews, pipeline checks, patch and dependency monitoring, and response support for businesses shipping changes through the year.
Frequently Asked Questions
Straightforward answers to the questions owners ask before getting started.
Is this a formal VAPT, or just an automated scan?
It is a formal vulnerability assessment and penetration test within an agreed scope. Automated tooling gives breadth, and a person then works through your application manually across every role, attempting the things a scanner cannot judge — reaching another customer’s records, bypassing an approval, or altering a value on the way to the server. You receive a scope document, a findings register with severity, evidence and reproduction steps, and a retest report, which is what a customer or auditor asking for VAPT normally expects to see.
Who actually performs the assessment?
Engineers who do security work, supported by penetration-testing specialists engaged for the scopes that need them. The proposal names who will do the work and what each person covers before you commit. Where we built the application ourselves, the review is done by someone other than the person who wrote it, because a reviewer checking their own code is not a review.
Will testing disturb our live application or our customers?
That is decided by you in the rules of engagement, not by us mid-test. Wherever a staging environment or a recent copy exists, we test there. On a live system we throttle activity, avoid destructive actions, schedule intensive work outside your busy hours, and keep an escalation contact on call. Anything that could affect real data, real orders or real customers is confirmed with you before it is attempted, and we log what was run and when so any coincidence during the window can be checked.
Do you help fix the findings, or only report them?
We help fix them, and this is the part most reports skip. After the walkthrough, each finding gets an owner, an approach and a place in the sequence. Your developers can implement the changes with our guidance and code review, or we make them ourselves where you have no capacity. Either way you end with a list where items are closed rather than a document that stays in a folder.
Is a retest included, and what evidence do we get?
A retest of the findings from the original assessment is included in the engagement, run within the window agreed in the proposal. We re-run the original reproduction steps and record the outcome for each item, then issue a retest report showing what is closed, what is still open, and what you have consciously accepted. Where a finding is accepted rather than fixed, that decision is written down with the reason and the person who took it.
Can you certify us for ISO 27001, SOC 2 or DPDP?
No. Certification is issued by an accredited certification body or an independent auditor, never by the vendor doing the technical work — and no one can certify you against India’s DPDP Act, which is a legal obligation rather than a certificate. What we do is the technology side that such an effort depends on: access control and logging, encryption, secure development practice, testing records, data-retention and consent handling, and the evidence an auditor will ask you to produce. We work alongside your consultant or auditor rather than in place of one.
Can you test an application another vendor built, and do you need the source code?
Yes, and no — source code is optional. A black-box assessment tests the running application, APIs and infrastructure from the outside using only test accounts, which is how we handle software built by a vendor who is no longer available. Source code enables a deeper secure code review of authentication, permissions, payments and queries, and finds issues that never surface externally. If you own the code, share it and you get more. If you do not, we work with what is running and tell you what that scope cannot cover.
Do you review our cloud, servers, databases and user permissions as well?
Yes, and for many businesses that part uncovers more than the application test. We review cloud storage exposure, network rules, roles and keys, patch levels, encryption, backup protection and logging, along with the database connection permissions and how credentials are stored. Separately we list every user, admin and integration account and compare it against what that job needs, which usually retires several logins belonging to people or vendors who left long ago.
How do you protect our data, and who owns the findings?
You own everything produced — the report, the findings register, the evidence, and the source code of any fixes we write, with repository access in your name. We sign a non-disclosure agreement before scoping. During testing we prefer test data over real records, use accounts you create for us, keep evidence to the minimum needed to prove a finding, mask personal data in screenshots, share the report over a controlled channel, and remove the working copies at the end of the engagement on a schedule you set. All credentials issued to us are yours to revoke at any time.
What drives the cost of a security assessment?
Cost follows scope and depth rather than a per-application price. The main drivers are how many applications, APIs, environments and cloud accounts are in scope, how many distinct user roles must each be tested, whether mobile builds are included, whether a source-code review is wanted alongside black-box testing, how much infrastructure and how many servers are covered, and whether you want us to carry out the fixes or only advise. Ongoing arrangements and repeat reviews are priced differently from a one-time assessment. You get an itemised proposal after scoping, broken up so lower-priority areas can be deferred to a later round.
What decides how long the work takes?
Access and scope decide it more than the testing itself. The factors are how quickly test accounts for every role and reviewer access to the cloud console are issued, whether a staging environment exists or testing must be scheduled around live business hours, the number of roles and the size of the application, whether code review and mobile builds are included, and — usually the largest factor — how fast your developers can turn the findings around, since the retest can only follow the fixes. Scoping gives you a schedule tied to those inputs rather than a number picked in advance.
What do you need from us, and will you train and support our team afterwards?
To start we need four things: the list of systems in scope with written authorisation from whoever owns them, test accounts covering every role, an agreed test window with one escalation contact, and a person who can decide priority when the findings arrive. Afterwards we train your developers on the specific mistakes found in your own code, show whoever manages access how to run a quarterly review, and hand over a short runbook covering the alerts and what to do about each one. Ongoing support covers periodic reassessment, patch and dependency monitoring, pipeline checks and help on the day something looks wrong.
