How We Test

What a manual assessment covers

Automated scanners are good at finding known vulnerabilities. They're not built to notice when three unrelated issues can be chained into something more serious, or when a piece of application logic can be abused in a way its designers didn't anticipate.

That's where manual testing earns its place, and it follows the five principles behind every engagement.

Authentication and session management

How login, session handling, and password reset flows stand up to direct attack and abuse.

Authorisation and access control

Whether one user can reach data or functionality that belongs to another.

Business logic and abuse cases

How the application behaves when used in ways it wasn't designed for, not just whether it does what it's supposed to.

API security

Endpoints tested directly, independent of the front end that calls them.

Injection and client-side vulnerabilities

SQL injection, cross-site scripting, and the other classes of flaw that come from unvalidated input.

Security misconfiguration

Settings, defaults, and deployment choices that create risk even when the underlying code is sound.

Privilege escalation

Whether a low-privilege foothold can be turned into administrative access.

Vulnerability chaining and post-exploitation impact

Attackers rarely stop at the first finding. We test whether individual issues can be combined into a more serious attack path, and what an attacker could reach from there.

Why Choose Exploitr

You work directly with your assigned consultant.

Our CREST-accredited penetration testing services are designed to uncover real, exploitable risks and provide organisations with practical guidance on how to fix them.

  • Direct access to your consultant, start to finish

    From the first scoping conversation to the final debrief, you'll deal with the consultant running your engagement and not an account manager or project coordinator acting as a go-between.

  • Scoped around your environment, not a standard template

    Every engagement starts with a conversation about your specific systems, risk profile, and objectives. The scope, methodology, and deliverables are built around what you actually need.

  • The same standard of testing, regardless of your size

    Whether you're a ten-person startup or a thousand-person enterprise, every engagement receives the same methodology, the same reporting standard, and the same level of attention throughout testing.

  • Reports written for your audience

    Every assessment includes a detailed technical report for the team responsible for remediation, and a clear executive summary for stakeholders who need to understand business risk without wading through technical detail.

  • Security visibility included as standard

    Every engagement includes access to the Exploitr platform at no extra cost, to provide a live view of findings as they're discovered, and not just a static PDF at the end. Track, manage, and remediate vulnerabilities in one place, throughout and beyond your assessment.

  • Fixed pricing, agreed before we start

    Every engagement is quoted at a fixed price before testing begins. No day rates, no scope creep, no surprises on the invoice. View our pricing guide.

Client Feedback

What our clients say

We don't publish client names. Protecting a client's identity is part of protecting the client, and we apply the same discretion to testimonials that we apply to every engagement.

All quotes below are authentic and shared with the client's consent.

I was honestly in the market for box-ticking, but Adam went well beyond the other vendors I'd spoken to. He's given me a lot of very meaningful improvements, and I'm extremely glad I went with Exploitr.

Based on our experience, I have no hesitation in recommending Exploitr, and will be engaging them again.
