Benefits and fit

What should a penetration test help you decide?

Leave with evidence of which weaknesses can really be exploited, what to fix first and confirmation that fixes for critical and high findings have worked.

Real attack path exposure

Burp Suite, Metasploit and Kali Linux tools actively exploit vulnerabilities to prove which CVEs can be chained into a full compromise. This gives security teams an honest picture of risk rather than a theoretical scan list with unchecked severity ratings.

A prioritised remediation roadmap

Every finding receives a CVSS score and a step-by-step fix recommendation. Critical and high findings include proof-of-concept evidence so developers understand the precise change required.

Evidence-grade compliance reports

CVSS-scored findings and OWASP Top 10 mapped reports give compliance leads concrete evidence for UK GDPR Article 32, ISO 27001 Annex A and Cyber Essentials submissions.

Retest verification included

Retesting critical and high findings after remediation confirms that fixes are effective before reports go to auditors or insurers. Verification reports document the before-and-after state for each finding.

Before you commit

Is VAPT the right starting point?

A good fit

You are an IT security manager, compliance lead or CTO at a London-regulated business and you need evidence-grade findings for UK GDPR Article 32 obligations, ISO 27001 audits or cyber insurance assessments.

A smaller change may be enough

If you only need weaknesses catalogued and ranked, a vulnerability assessment identifies them with automated scanning tools and scores each finding. A penetration test goes further and exploits them to determine real-world impact.

What we deliver

What your VAPT engagement covers

Expand a target type to see the tests and outputs. A scoping call confirms what is in scope before testing starts.

Web application penetration testing

Security teams get OWASP Top 10 web application tests using Burp Suite Professional and manual validation.

Authentication bypass, SQL injection, cross-site scripting, insecure direct object reference and broken access control findings are CVSS-scored and mapped to CWE references.

Retest verification confirms remediation before compliance submissions.

Network and infrastructure VAPT

IT managers get internal and external network assessments using Nmap, vulnerability scanners and Metasploit exploitation validation.

Open ports, unpatched services, misconfigured firewalls and lateral movement paths are documented with CVSS scores.

Findings map to ISO 27001 Annex A controls and NCSC Cyber Essentials requirements for straightforward compliance evidence.

REST API security testing

Development teams get REST API testing against OWASP API Security Top 10, covering broken object level authorisation, authentication failures, excessive data exposure and server-side request forgery.

Burp Suite intercept and custom scripts validate each endpoint. Findings include exploit code samples and precise developer fix instructions mapped to CWE identifiers.

Cloud penetration testing for AWS and Azure

Cloud engineering teams get AWS and Azure penetration testing covering IAM policy misconfigurations, S3 bucket exposure, network security group gaps, container security and serverless function vulnerabilities.

Findings follow NCSC cloud security guidance and map to ISO 27001 risk controls. Scoping calls confirm permission boundaries and rules of engagement before testing begins.

Vulnerability assessment and CVSS reporting

Compliance teams get automated and manual vulnerability assessments that score every finding against the Common Vulnerability Scoring System.

Reports include CVE references, asset risk ratings, board-ready executive summaries and a prioritised remediation plan.

Outputs satisfy UK GDPR Article 32 technical measures and support ISO 27001 Statement of Applicability updates.

Testing capabilities

Which tools and standards does the testing use?

Six technical capabilities sit behind every report.

Burp Suite Professional

Intercepting proxy, scanner and intruder modules test every web application request for injection, authentication and access control flaws.

CVSS scoring and CVE mapping

Every finding receives a CVSS v3.1 base score and a CVE or CWE reference so development teams prioritise fixes by verified risk severity.

OWASP Top 10 methodology

Web and API testing follows OWASP Top 10 and OWASP API Security Top 10, ensuring complete coverage of the most critical application risks.

Nmap and Metasploit exploitation

Network scanning with Nmap identifies open services. Metasploit validates exploitability, proving which vulnerabilities pose genuine compromise risk.

Cloud security testing

AWS and Azure assessments cover IAM, storage, networking and container security against NCSC cloud guidance and ISO 27001 risk controls.

Retest and verification reports

Post-remediation retests confirm critical and high findings are resolved. Verification reports provide before-and-after evidence for audit submissions.

Our process

From scoping call to a verified fix

Softomate maps scope, defines rules of engagement, executes controlled testing, scores findings against CVSS and delivers actionable remediation reports in short delivery phases. IT security contacts, compliance leads and technical owners stay involved from scoping through retest verification.
