Independent UK Cyber Security Consultancy
Penetration Testing & Attack Path Simulation
We test your defences the way an attacker would, identifying exploitable weaknesses before they are found by others. Every engagement is formally scoped, contracted, and delivered with clear findings that technical and executive audiences can act on.
About
Secured By Offense
Secured By Offense is an independent cyber security consultancy based in the United Kingdom. We provide penetration testing, cyber security audits, attack path simulation, and Cyber Essentials certification support to organisations across the private and public sectors.
Our work is grounded in current offensive security techniques and aligned to NCSC guidance and recognised industry frameworks. All findings are documented with risk ratings and practical recommendations, structured to be understood at board level and acted upon by technical teams.
Every engagement is governed by a formal written contract, signed Rules of Engagement, and a Non-Disclosure Agreement, providing legal certainty for both parties from the outset.

What We Do
We work across the full spectrum of offensive security, from government-backed certification through to complex adversary simulation.
Web Application & API
Manual penetration testing of web applications and APIs conducted in accordance with OWASP methodology. The assessment identifies authentication weaknesses, injection vulnerabilities, business logic flaws, and access control failures beyond the reach of automated scanning. Findings are delivered with full technical detail, risk ratings, and prioritised remediation steps.
Internal Infrastructure Assessment
Assessment of services and software running within a specified network range. Domain credentials are not required but can be provided to assess from both an authenticated and unauthenticated perspective. Covers vulnerability identification, service misconfiguration, and exposure across the internal network, delivering a risk-rated findings report.
Attack Path Simulation
A fully comprehensive infrastructure assessment with all systems within scope. Conducted from a position of provided credentials or a provisioned corporate device, the engagement tests every viable attack path across on-premise and cloud environments, including Azure, AWS, and GCP. Each path leading to a defined objective, typically administrative access to a system, is documented in full, producing a structured record of exploitable routes through your environment.
Cyber Essentials Certification
Structured preparation for Cyber Essentials and Cyber Essentials Plus certification. The NCSC-backed scheme is a requirement across many public sector and supply chain contracts. We conduct a gap assessment against the five technical control areas, provide remediation guidance for identified weaknesses, and carry out a pre-submission review to support first-time certification.
