Discover

VAPT discovery and scoping workshop

Business context, compliance requirements and asset inventory are mapped in a scoping call with IT security managers, developers and compliance owners. Discovery produces a target list, rules of engagement document and test schedule agreed before any active testing begins.

Plan

VAPT planning and methodology selection

Testing methodology, OWASP Top 10 coverage depth, CVSS reporting thresholds and delivery timeline are agreed with IT and compliance stakeholders. Planning produces a signed rules of engagement document, test schedule and acceptance criteria aligned to UK GDPR, ISO 27001 or Cyber Essentials requirements.

Design

VAPT test case design and attack scenario planning

Attack scenarios, test cases and tool configurations are designed for each target. Web application tests plan Burp Suite intercept flows. Network tests plan Nmap discovery sequences and Metasploit exploitation paths. Cloud tests plan IAM enumeration and privilege escalation checks. Design outputs a test case inventory approved before active testing.

Build and Integrate

VAPT active penetration testing and exploitation

Active testing, exploitation and finding validation are executed within agreed scope boundaries. Burp Suite, Nmap, Metasploit and Kali Linux tools produce evidence screenshots, request logs and exploit proof-of-concept data for every finding. Critical vulnerabilities trigger immediate client notification before the full report is drafted.

Launch and Optimise

VAPT report delivery and remediation retest

Final CVSS-scored report, executive summary and remediation roadmap are delivered within five working days of testing completion. A debrief call walks technical and compliance teams through priority findings. Retest verification confirms critical and high issues are resolved before audit submissions or insurance renewals.

09. FAQs

Common Questions About Penetration Testing and VAPT

A vulnerability assessment identifies and catalogues security weaknesses using automated scanning tools such as Nmap and Burp Suite. Each finding receives a CVSS score to rank severity. A penetration test goes further: a tester actively exploits those weaknesses using Metasploit and Kali Linux to determine real-world impact. Vulnerability assessments produce a prioritised remediation list. Penetration tests prove which CVEs an attacker could chain together to compromise your systems. NCSC guidelines recommend both for UK businesses handling personal data under UK GDPR.

Penetration testing for London businesses typically starts at £1,800 for a focused web application test and rises to £10,000 or more for a full infrastructure VAPT engagement. Scope, number of targets and OWASP Top 10 methodology depth affect the price. Softomate provides fixed-price quotations following a scoping call. All pricing includes a written report with CVSS-scored findings, an executive summary and a step-by-step remediation roadmap. Retesting to verify fixes is included in the engagement fee.

A standard web application penetration test takes three to five working days. Infrastructure VAPT for a mid-sized London network typically takes five to ten days. Cloud penetration testing on AWS or Azure varies by the number of services in scope. REST API testing adds one to two days for complex integrations. Softomate agrees all timelines at the scoping stage. A draft report is delivered within five working days of testing completion. A final report with a remediation plan follows after client review.

A Softomate VAPT report includes an executive summary suitable for board and senior management review. The technical section lists every finding with its CVSS score, CWE reference, evidence screenshots and a step-by-step remediation recommendation. An appendix documents the testing methodology, tools used including Burp Suite, Nmap and Metasploit, and scope boundaries. Reports align to OWASP Top 10 and NCSC guidelines. A retest offer verifies that critical and high findings have been remediated before your team shares results with auditors or insurers.

Yes. Softomate delivers cloud penetration testing for AWS and Azure environments. Tests cover IAM misconfigurations, storage bucket exposure, network security group rules, container security and serverless function vulnerabilities. Testing follows NCSC cloud security guidance and ISO 27001 risk assessment principles. Findings receive CVSS scores and are mapped to CWE references so your engineering team can prioritise fixes. A scoping call confirms service inventory, permission boundaries and rules of engagement before testing begins.

Yes. Regular penetration testing and vulnerability assessments provide concrete evidence of security controls for UK GDPR Article 32 technical measures and ISO 27001 Annex A controls. ICO enforcement cases frequently cite the absence of regular security testing as a contributing factor to data breaches. Softomate VAPT reports map findings to specific ISO 27001 controls and NCSC Cyber Essentials requirements. This gives your compliance team actionable evidence for DPA 2018 obligations and audit submissions.

NCSC guidance recommends at least annual penetration testing for most UK organisations. Businesses subject to FCA oversight, UK GDPR processing of special category data or PCI DSS scope should test at least twice a year. Significant infrastructure changes, new application releases or cloud migration events should trigger additional scoping and testing. Softomate offers retainer-based VAPT programmes that schedule assessments quarterly or semi-annually. Clients receive continuity of testing methodology, baseline comparisons and year-on-year trend reporting across CVSS scores.
