What this actually is

Some estates are too large to test one application at a time. A bank with forty internal systems. A government department with a dozen citizen portals. A group whose subsidiaries each built their own stack.

Enterprise testing is a programme rather than an engagement. We build the inventory, tier assets by what they would cost you if they failed, and run a rolling schedule so the things that matter get tested more often than the things that do not.

The point is coverage you can defend to a regulator, and a trend line that shows whether your posture is actually improving year on year.

What we go after

  • Full estate discovery and asset inventory
  • Risk tiering by business impact and exposure
  • Rolling test schedule across applications, APIs and infrastructure
  • One methodology and one reporting standard across every business unit
  • Central findings register with ownership and ageing
  • Trend reporting across quarters and years
  • Regulator-ready coverage evidence

How we run it

  1. 01

    Scope and authorise

    Targets, testing windows, escalation contacts and safety limits, all agreed in writing before anyone touches anything.

  2. 02

    Map the surface

    We enumerate what is actually exposed, which is usually more than the asset register says.

  3. 03

    Test by hand

    Tooling gives coverage, our engineers give proof. Every finding is reproduced before it is written down.

  4. 04

    Report

    An executive narrative your board can act on, and a technical annexe with the exact request, payload and fix.

  5. 05

    Re-test and sign off

    Once you have fixed it we verify each one at no extra cost, then close the engagement properly.

What you receive

  • Asset inventory with risk tiering
  • Annual testing calendar
  • Consistent per-asset reports
  • Central findings register in AppSec 360
  • Quarterly executive trend report

Who needs this

Banks, large enterprises, government departments and groups with multiple business units that need consistent evidenced coverage rather than one-off tests.

How long it takes

Set up in four to six weeks, then a rolling annual programme.

Standards this satisfies

  • ISO 27001
  • CERT-In
  • RBI
  • SEBI CSCRF
  • PCI DSS

Why it matters

Testing exists to answer a question somebody outside your team is asking: a customer, an insurer, a regulator, or a board that wants to know whether the money spent on security bought anything. A scan report does not answer it. A test that names what was verified, to what depth and against which standard does.

The second reason is more practical. Controls decay. Configurations drift, integrations get added under deadline, and the environment you tested last year is not the one running today. Testing is how you find out which of your assumptions stopped being true.

Choose the depth you actually need

Most of the price difference between quotes comes down to this one choice, and it is rarely explained. Pick one to see what it covers, what it suits and what it costs you.

You give us working accounts at each privilege level and a short walkthrough. We then test what a real attacker reaches after the first stolen password, which is where the findings that matter almost always live. This is what we recommend for most engagements.

Choose this when

  • Any application with authenticated functionality
  • Multi-tenant products, where tenant isolation is the real risk
  • Getting the most findings for the money

Effort and cost

Moderate effort and by far the best coverage per rupee. Most of the serious findings we report come out of authenticated testing rather than unauthenticated.

Tested against OWASP ASVS, not a checklist we invented

We test to the OWASP Application Security Verification Standard, which sets verification levels across authentication, session management, access control, input validation, cryptography, error handling and business logic. Working to a published standard means you can tell an auditor or a customer exactly what was verified and to what depth. It also makes this year's test comparable with last year's, which a bespoke in-house checklist never is.

Scope it yourself, before you call anyone

Answer a few questions and you get an indicative number, the working behind it and what your answers tell us. It runs in your browser, so nothing you type reaches us.

What needs testing?

Pick everything in scope. Effort is driven by unique functionality, not by how many IP addresses you own.

What we look for, and keep finding

These are the classes of problem this work exists to surface. Not every engagement finds all of them, but these are the ones that turn up often enough to be worth naming.

  • Broken access control

    The most common serious finding we report, and the one scanners miss most reliably. An identifier that is not checked against the caller, an admin function reachable by guessing its path, a role that can be changed in the request. The user is logged in. They are simply reading or doing something that is not theirs.

  • Injection and unsafe query construction

    SQL, NoSQL, OS command and template injection. Modern frameworks prevent most of it, which is exactly why the remaining cases hide in the hand written query somebody added under deadline, or in the reporting module nobody has looked at since it shipped.

  • Authentication and session weaknesses

    Tokens that do not expire, password reset flows that can be redirected, multi-factor that can be skipped by replaying an earlier step, and sessions that survive a password change. We test the whole lifecycle rather than just the login form.

  • Business logic abuse

    Nothing is technically broken. The application simply allows a sequence it should not: a discount applied twice, a payment confirmed before it clears, a limit avoided by splitting a request. This requires understanding what the application is for, which is why automation cannot find it.

  • Sensitive data exposure

    Data returned by an API that the interface never displays, secrets in client side code, verbose errors that reveal structure, and personal data in logs. The response body is where we find most of it.

  • Security misconfiguration

    Default credentials, directory listing, debug endpoints reachable in production, permissive CORS and missing security headers. Individually minor, and routinely the first step in a chain that ends somewhere serious.

Who runs your engagement

A senior tester, named before you sign

Testing is led by an engineer holding OSCP, CREST or equivalent, and you are told who it is before the engagement starts. They write the report themselves rather than handing notes to someone else, and they are on the call when findings are walked through. If the person changes, we tell you why.

Questions we get asked

Can this replace our individual testing budgets?

Usually it consolidates them and costs less overall, because we are not rescoping from scratch every time and the same team already knows your estate.

How do you decide what gets tested most often?

Business impact first, then exposure, then rate of change. An internet-facing payment system that ships weekly gets tested far more often than an internal reporting tool that has not changed in two years.
