External infrastructure
Your internet-facing systems, tested the way an outside attacker would approach them.
Find the weaknesses before attackers do.
We combine human-led penetration testing by CREST-accredited testers with continuous testing by AI agents. Expert testers find what automation misses. AI agents keep testing between engagements. You see every finding, fix and retest on a single platform.
Works well with Managed Cyber Resilience. Available on its own or alongside a plan. Every plan includes continuous vulnerability scanning and an annual basic web application test, and Sentinel adds an annual penetration test of agreed scope. Penetration Testing adds deeper, more frequent and broader testing, from a single application test to a full red team exercise. See what every plan includes
Testing
Expert testers and AI agents. One continuous programme.
A yearly test shows your security on one day. Continuous testing shows it every day. Together they give you depth and coverage.
CREST-accredited testers use the creativity and judgement that automation cannot match. They test against recognised methods, such as the OWASP testing guides, and explain each finding in plain English.
Internal network
What an attacker could reach after a compromised laptop or account gets them inside.
Web applications and APIs
Authentication, access control, business logic and data exposure, tested by hand.
Cloud and Microsoft 365
Configuration, identities and permissions in AWS, Azure, Google Cloud and Microsoft 365.
AI applications and agents
Prompt injection, tool misuse and data leakage in the AI systems you build or deploy.
Social engineering
Phishing and pretexting exercises that test how your people respond to a convincing attack.
AI agents test your systems all year round. They work like an attacker: they map your exposure, try techniques and chain weaknesses together. Their findings join your human-led results on the same platform.
Always testing
AI agents probe your systems continuously, not once a year. New exposure is found in days, not months.
Thinks like an attacker
Agentic testing chains weaknesses together to find real attack paths, beyond what a vulnerability scanner reports.
Proves exploitability
Findings come with evidence that the weakness can be used, so your team does not chase theoretical issues.
Follows your changes
New releases, services and cloud resources are tested as they appear.
A red team exercise is a realistic, objective-based attack on your whole organisation. It tests whether an attacker could reach what matters most, and whether your people and your monitoring would notice in time.
With Managed Cyber Resilience, a red team exercise also tests the 24/7 detection and response that protects you every day.
Every red team exercise includes
- Objectives agreed with you, such as reaching finance systems or client data
- Rules of engagement that protect your operations
- Attacks across people, processes and technology
- A test of how quickly your monitoring detects and responds
- A debrief with your leadership and technical teams
- A prioritised plan to close the gaps
One platform
Every finding. One place.
Human-led tests, continuous testing and red team results all arrive on the same platform. Your team sees what to fix and how. Your leadership sees the trend. You never wait weeks for a PDF report.
On the platform
- Human-led and continuous findings in one place
- Evidence, impact and fix guidance for each finding
- Retest status, so you know when a fix works
- Trends over time for your leadership team
- Reports for clients, insurers and auditors
How it works
From scope to proven fix.
We scope and quote each engagement individually, from a single application test to a year-round testing programme.
-
Scope
We agree the targets, the objectives, the timing and the rules of engagement.
-
Test
Testers and AI agents work through the scope, with no surprises for your operations.
-
Report
You receive clear findings, ranked by risk, with an executive summary and technical detail.
-
Fix
We help your team or IT provider plan and prioritise the remediation.
-
Retest
We confirm each fix and update your results on the platform.
