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 access control

How login, session handling and password reset flows stand up to attack, and whether one user can reach another's data or functionality.

Business logic and abuse cases

What happens when workflows are run out of order, repeated or tampered with, beyond whether the application does what it's supposed to.

API security

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

Injection and misconfiguration

SQL injection, cross-site scripting and other flaws that come from unvalidated input, plus settings and defaults that create risk even when the 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.

  • Critical findings raised straight away

    If your consultant finds something serious during testing, you hear about it immediately rather than waiting for the final report.

  • 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.

  • Reports written for your audience

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

  • Fixed pricing, agreed before we start

    Every engagement is quoted at a fixed price before testing begins, rather than open-ended day rates, so there's no scope creep and no surprises on the invoice. View our pricing guide.
