Penetration Testing
What could a real attacker take from you? Our penetration tests answer that question with evidence, not a list of vulnerabilities: our experts challenge your systems with attacker techniques in an authorised, controlled way, chain weaknesses together to expose the paths to your critical data and systems, and report every finding with its business impact.
TSE TS 13638 accredited
Our methodology, team and reporting processes are independently audited.
Validated findings only
Every finding is proven through exploitation; scanner noise never reaches your report.
With you until closure
Once fixes are in place, we retest and report that the findings are closed.
Attack paths, not vulnerability lists
Automated scanners list known vulnerabilities; they do not tell you which ones are truly dangerous. Real attacks rarely come from a single critical flaw. They come from chaining weaknesses that look harmless on their own: a leaked configuration, a weak authorisation check and a misplaced trust relationship together open the way to customer data.
That approach is at the centre of our testing. Our experts think like attackers, understand your business logic and authorisation model, connect the findings and answer “what happens if this is not fixed?” with a concrete attack scenario. Your teams can then focus on the fixes that reduce the most risk.
What we test
Application security
Web applications, mobile apps (iOS, Android), REST and GraphQL APIs; authorisation, session management and business logic flaws.
Network and infrastructure
External and internal networks, Active Directory attack paths, segmentation, remote access and wireless networks.
Cloud
Configuration, identity and access management, exposed resources and cross-account privilege escalation in AWS, Azure and GCP.
AI and LLM applications
Prompt injection, data exfiltration and abuse of model and agent permissions.
Enterprise and critical systems
SAP environments, OT/ICS and IoT infrastructure, tested with a dedicated plan that protects operational continuity.
Human and physical layer
Social engineering tests with phishing, vishing and physical access scenarios.
What sets us apart
- Experts do the testing, not tools: our team of TSE senior penetration testers and OSCP, OSCE, CRTO and CISSP certified consultants runs every test themselves; we never subcontract the work.
- Evidence-based reporting: every finding comes with reproducible steps, request/response samples and screenshots; false positives are removed before reporting.
- Attack chains and business impact: we treat findings as the path an attacker would follow, not as isolated issues, and prioritise risk by business impact alongside the CVSS score.
- No waiting on critical findings: if we find a critical vulnerability during testing, we notify your team without waiting for the report.
- Retesting included: once your fixes are complete, we retest the findings and report their closure.
- We build our own platforms: our attack surface management (OmniRoot) and finding management (OmniTrack) platforms are products of the R&D work that feeds our testing.
How we work
- Scoping and threat modelling: together we define your business goals, critical assets and the threat scenarios you may face, and put the scope, approach (black, grey or white box) and rules of engagement in writing.
- Reconnaissance and attack surface analysis: we map the target systems, services, user roles and possible entry points.
- Manual testing and exploitation: based on OWASP WSTG, MASTG, PTES and NIST SP 800-115, focusing on the authorisation and business logic flaws that tools miss.
- Analysis and reporting: we assess findings within the attack chain, prioritise them by business impact and walk through them with your technical teams in a debrief meeting.
- Retest and closure: we retest the fixes and report their closure in an audit-ready format.
What you receive
- An executive summary focused on business risk for management and the audit committee
- A technical findings report with CVSS scores, reproducible steps and evidence
- Attack scenarios showing the paths to critical data
- Prioritised, actionable remediation guidance and a debrief meeting
- A retest report usable in BDDK, CBRT, PCI DSS, ISO 27001 and DORA audits
From one-off tests to continuous assurance
An annual test only captures a snapshot of that day, while your applications and infrastructure change with every release. We help organisations move their security testing from projects to programmes: an annual testing calendar, tests tied to critical releases, continuous monitoring of internet-facing assets, and tracking of every finding with its owner, deadline and closure.
Continuous monitoring is covered by our attack surface management service, and finding tracking by our upcoming OmniTrack platform.
Frequently asked questions
What is the difference between a penetration test and a vulnerability scan?
A vulnerability scan uses automated tools to list known vulnerabilities; the results often contain false positives and do not show whether a weakness can actually be exploited. A penetration test is manual work in which experts chain and exploit those weaknesses like a real attacker, also uncovering privilege escalation, authorisation and business logic flaws that scanners cannot detect. The result is not a list of findings but a prioritised picture of risk that proves how far an attacker could get.
What should you look for when choosing a penetration testing company?
Check that the company’s TSE accreditation is valid and that the testing team includes certified testers with hands-on certifications such as OSCP, OSCE and CRTO. Ask for a sample report: the difference between a report that proves every finding with exploitation evidence and reproducible steps and one that simply reformats scanner output is obvious at first glance. Make sure the test is not subcontracted, that the confidentiality and disposal of test data are handled properly, and that retesting is included in the quote. Quotes far below the market average usually rely on automated scanning instead of manual testing.
How often should penetration testing be done?
Common practice is to test critical systems at least once a year and after every significant change, such as a new application, a major release or an architectural change. Some regulations make this frequency mandatory.
Can a penetration test damage live systems?
Tests are run in a controlled way under the rules of engagement; techniques that could cause service disruption are only used with written approval and in agreed time windows. Testing in a staging environment is also possible for critical systems.
How is the price of a penetration test determined?
The price depends on the number of applications, IP addresses and user roles in scope, the type of test (black, grey or white box) and reporting requirements. Share your scope and we will prepare a tailored quote.
