Vulnerability Assessment
Authenticated scanning of servers, endpoints, network devices and web applications to find known weaknesses, ranked by real exploitability rather than raw severity scores.
Capability overview
What vulnerability assessment involves
A vulnerability assessment finds known weaknesses across a broad estate: missing patches, outdated software, weak configurations and exposed services. It is wide and repeatable, which makes it the right tool for regular hygiene, whereas a penetration test goes deep on a smaller scope.
The value is in prioritisation. A scan of a few hundred hosts can produce thousands of findings, so we remove false positives and rank what remains using CVSS severity, the EPSS exploit probability score and whether the flaw appears on the CISA Known Exploited Vulnerabilities list.
What is included
What is assessed
External attack surface
Internet-facing IP ranges, domains and cloud endpoints, including forgotten test servers and services exposed by mistake.
Internal infrastructure
Credentialed scans of Windows and Linux servers, workstations, hypervisors and network devices from inside the network.
Web applications
Automated dynamic scanning for common weaknesses such as injection, outdated libraries and missing security headers.
Configuration baselines
Selected systems compared against CIS Benchmarks to catch insecure defaults that patching alone will not fix.
How we work
How we deliver vulnerability assessment
Asset discovery
In-scope ranges and applications confirmed, and discovery sweeps run to find assets missing from the inventory.
Scanner setup
Scan accounts with least privilege created and scan windows agreed so production performance is not affected.
Scanning
Authenticated and unauthenticated scans run using tools such as Nessus, OpenVAS or your existing scanner licence.
Triage
Findings verified manually where results are doubtful, duplicates merged and exploitability data applied to set priority.
Remediation guidance
Fix instructions grouped by owner team, with a rescan after the agreed window to confirm closure.

Penetration Testing
Manual, intelligence-led attacks on your applications, networks and cloud accounts by testers who chain weaknesses together to show what a real attacker could reach.
Web Application Security
Protection for live websites and web applications: hardened configuration, a tuned web application firewall, bot and abuse controls, and fixes for OWASP Top 10 weaknesses in production.
Application Security
Security built into how your software is designed, coded and released: threat modelling, secure code review, SAST and dependency scanning in the pipeline, and developer training.
API Security
Discovery, testing and protection of the APIs behind your mobile apps, partner integrations and microservices, focused on the authorisation flaws attackers exploit most.

Questions about Vulnerability Assessment

Ask a questionInternet-facing assets benefit from monthly or continuous scanning. Internal estates are commonly scanned quarterly, with an extra scan after major changes or when a critical flaw is published.
No. An assessment identifies and ranks known weaknesses across many systems. A penetration test tries to exploit and chain weaknesses to show what an attacker could actually achieve.
One-off assessments are fixed price based on the number of IP addresses and applications in scope. Recurring scanning is offered as a subscription with a set number of scans and rescans per quarter.
A prioritised findings register you can import into your ticketing tool, a short management summary showing exposure by business unit, and a rescan report confirming which issues were closed within the agreed window.
