Cybersecurity services

Think like an attacker.
Defend like an engineer.

Ten specialist services, one shared picture of your attack surface. Every engagement starts with GapSecure ASM, so our experts spend their time on what's actually exposed.

Project

A fixed-scope engagement such as a pentest, code review or cloud assessment, with a clear report and retest.

Retainer

A bank of expert days to use across services through the year, with priority scheduling.

Continuous

ASM platform plus managed services (SOC, BAS, threat intel and periodic testing) run as one programme.

How attackers get in

Every service breaks a different link in the chain.

Real attacks move left to right, from a forgotten asset to your crown jewels. Below, each service shows exactly where it stops that chain. Here is the whole chain, and how GapSecure cuts it at the source.

01 · Offensive

Red Teaming

Find out whether a determined adversary could reach your crown jewels, and whether you would notice in time.

Our red team emulates the actors most likely to target your sector, chaining technical, human and physical weaknesses toward agreed objectives. Unlike a penetration test, the goal isn't a list of bugs. It's an honest measure of your organisation's ability to prevent, detect and respond to a real attack.

Vulnerability Assessment & Penetration Testing

Find and prove exploitable weaknesses before attackers do, with every finding verified and reproducible.

We combine broad automated discovery with deep manual testing by experienced testers. Business-logic flaws, broken authorisation and chained exploits (the issues scanners miss) are where we spend our time. Each issue comes with impact, reproduction steps and clear remediation, and we retest your fixes at no extra cost.

Secure Code Review

Catch vulnerabilities at the source, where they're cheapest to fix and impossible to miss.

Automated tools find patterns; people find intent. We pair SAST and SCA baselines with expert manual review of the code paths that matter most (authentication, authorisation, cryptography, data handling and business logic) and deliver fixes your developers can paste straight in.

DevSecOps

Make security a property of the pipeline, not a gate at the end of it.

We design and embed security controls directly into your CI/CD so that every commit, build and deploy is checked automatically, with risk-based gates that block what matters and stay out of the way of everything else. Then we enable your developers to own it.

Cloud Security Assessment

One misconfigured bucket or over-privileged role is all it takes. Find them first.

We review your AWS, Azure and GCP estates against industry benchmarks, then go further: tracing identity and network paths across accounts to show how an attacker who lands in one place could reach your most sensitive data, and how to cut those paths.

06 · Validation

Breach & Attack Simulation

Stop assuming your controls work. Prove it, continuously.

Security tools drift. Rules get disabled, agents go missing, configurations change. BAS safely replays real attacker techniques in your environment on a schedule, scoring which were prevented, which were detected and which slipped through, then helps you close every gap.

07 · Intelligence

Threat Intelligence

Know who is targeting you, how they operate and what they already have, before they use it.

We collect across open, deep and dark sources, then correlate what we find with your real attack surface in GapSecure ASM. The result is intelligence you can act on: leaked credentials to reset, lookalike domains to take down, and exploited vulnerabilities on hosts you actually run.

08 · Detection

Threat Hunting

Assume they're already in. Then go and find them.

Sophisticated adversaries live off the land and avoid triggering alerts. Our hunters work from intelligence-led hypotheses across your endpoint, identity, network and cloud telemetry to uncover hidden activity, and every successful hunt becomes a new detection rule for your SOC.

09 · Operations

Managed SOC

Eyes on glass 24×7×365, with analysts who already know your attack surface.

Our SOC monitors, triages and responds around the clock. Because it shares context with GapSecure ASM and our threat intelligence, an alert on an internet-facing host comes with what's exposed, what's vulnerable and who is exploiting it, so containment starts in minutes, not hours.

Compliance Audits

Pass the audit and come out genuinely more secure than you went in.

From first gap assessment to certification day, we guide you through the frameworks your customers and regulators demand. Technical controls are evidenced directly from GapSecure ASM's compliance mapping, so your team spends less time collecting screenshots and more time closing gaps.
