The client
A UK-based financial services organisation operating within a highly regulated environment required greater visibility across its internet-facing infrastructure and vulnerability exposure.
With increasing regulatory scrutiny, growing cyber insurance expectations, and a lean internal IT function, the organisation needed a more scalable and proactive approach to vulnerability management.
Peritus Cloud Security partnered with the client to implement a managed continuous vulnerability exposure management programme powered by AppCheck.
The challenge
The organisation relied heavily on periodic penetration testing and manual vulnerability assessments to identify security weaknesses.
While valuable, these assessments only provided a snapshot of risk at a single point in time — leaving long periods where newly introduced vulnerabilities could remain undetected.
Key challenges included:
- Limited visibility between testing cycles
- Difficulty prioritising remediation activity
- Increasing compliance and governance pressure
- Small internal resource managing growing exposure
- Lack of continuous monitoring across internet-facing assets
- Time-consuming reporting and remediation coordination
The client required a solution that would improve operational visibility without introducing significant management overhead.
The Peritus approach
Peritus designed and delivered a managed continuous vulnerability exposure management service using AppCheck’s continuous scanning platform.
The engagement focused not only on vulnerability detection, but also on operational support, remediation prioritisation, governance reporting and measurable security improvement.
Continuous vulnerability monitoring
Peritus implemented continuous external vulnerability scanning across the client’s public-facing infrastructure, enabling risks to be identified as they emerged rather than waiting for periodic assessments.
Risk-led remediation support
Security findings were assessed and prioritised by Peritus consultants based on exploitability, operational impact and exposure risk — helping internal teams focus remediation activity where it mattered most.
Governance and reporting
Peritus delivered structured reporting suitable for both technical teams and executive stakeholders, improving governance visibility and simplifying compliance discussions.
Attack surface visibility
The organisation gained a clearer understanding of externally exposed assets, helping reduce unmanaged or forgotten services and improving overall attack surface awareness.
The outcome
Within the first 90 days of deployment, the organisation achieved measurable improvements across visibility, remediation and operational maturity.
Key outcomes included:
- 72% reduction in critical internet-facing vulnerabilities
- Improved remediation response times
- Greater visibility across externally exposed assets
- Reduced operational reliance on reactive testing cycles
- Improved governance and reporting capability
- Increased confidence in external security posture
By shifting from reactive assessments to continuous monitoring, the client significantly reduced vulnerability exposure windows and improved overall security resilience.
Client feedback
“Peritus gave us continuous visibility we simply didn’t have before. Instead of waiting for periodic testing reports, we now have ongoing assurance and clear guidance on where to focus remediation efforts.”
