Penetration Testing Derby
Precursor Security provides CREST-accredited penetration testing in Derby, including infrastructure, web application, wireless, and physical intrusion testing. Derby's aerospace and rail engineering economy places many local businesses inside defence and critical supply chains, where accredited security testing is a contractual requirement; our CREST accreditation and BPSS-cleared testers meet those demands, with on-site delivery across the East Midlands.
CREST-accredited penetration testing for Derby organisations: infrastructure, web applications, wireless, and physical intrusion testing, built for the assurance demands of aerospace, rail, and advanced manufacturing supply chains.
Assurance-grade testing for an
engineering city.
Derby has one of the highest concentrations of engineering employment in the UK, anchored by aerospace and rail. That puts hundreds of local suppliers inside defence and critical national infrastructure supply chains, where security questionnaires, Cyber Essentials Plus, and accredited penetration testing are now conditions of doing business. We deliver testing that stands up to prime contractor scrutiny: CREST-accredited methodology, BPSS-cleared testers as standard, and reporting that slots directly into supply chain assurance evidence.
Who We Test In Derby
Testing scoped to the sectors that define Derby's economy, because a meaningful penetration test starts from who actually attacks businesses like yours, and what they are after.
How We Reach You
Derby is served from our Leeds headquarters. Around 90 minutes from Derby via the M1.
CREST-Accredited, Verifiably
Precursor Security holds CREST organisational accreditation for penetration testing, independently audited across methodology, QA, and tester competency. Every engagement letter carries our membership number for direct verification by your auditors, insurers, or customers.
No Travel Games. No Scanner Reports. No Offshoring.
Derby clients get the same team, methodology, and day rate as our London and Leeds clients: manual testing by employed, UK-based CREST Registered Testers, fixed quotes agreed at scoping, immediate escalation of critical findings, and free retesting of everything you fix. On-site internal, wireless, and physical intrusion testing across Derby, Derbyshire, and the wider East Midlands.
Every Test,
Delivered In Derby.
The full offensive security portfolio is available to Derby organisations. Each service links to its full methodology, and every engagement ends with reporting your engineers can action and your auditors can file.
Web Application Penetration Testing Derby
Manual, CREST-accredited testing of the web applications and APIs your Derby business depends on. Full OWASP coverage plus the business logic and access control flaws automated scanners miss, with free retesting of every finding.
Internal & External Network Testing Derby
External testing of your internet-facing perimeter, and internal testing that maps what an attacker could reach once inside: Active Directory attack paths, lateral movement, and privilege escalation. On-site delivery in Derby.
Cloud Penetration Testing Derby
Configuration review and attack-path testing across AWS, Azure, Microsoft 365, and GCP. We find the identity misconfigurations, exposed storage, and over-privileged roles that cause most real cloud breaches.
Wireless Network Testing Derby
On-site assessment of your wireless estate in Derby: rogue access point detection, segregation between guest and corporate networks, and attacks against enterprise authentication.
Mobile Application Testing Derby
iOS and Android application assessments covering insecure storage, API trust boundaries, and platform hardening, for Derby businesses shipping mobile products or internal apps.
Cyber Essentials & Compliance Derby
Cyber Essentials and Cyber Essentials Plus certification, ISO 27001 support, and PCI DSS testing for Derby organisations that need recognised certification alongside technical assurance.
Threat Detection & Response for Derby, 24/7.
A penetration test proves what an attacker could do today. Our UK Security Operations Centre watches for the ones who try tomorrow: managed detection and response, a CREST-accredited SOC, and incident response for Derby organisations, delivered entirely from UK soil.
Explore Defensive SecurityHow Engagements Run In Derby.
From first call to free retest. Every Derby engagement is managed by a named account manager with direct access to the testing team, no ticket queues between you and the people doing the work.
Scoping & Fixed Quote
A free scoping call, usually within 24 hours of your enquiry, where a technical consultant (not a salesperson) defines what needs testing, agrees the approach, and produces a fixed quote. Derby clients can scope by video call or, where practical, in person via our Leeds headquarters.
Testing In Derby
CREST Registered Testers execute the engagement during agreed windows: remote phases for external, web, and cloud testing, and on-site or appliance-based delivery for internal and wireless work in Derby. You get daily progress updates, and critical findings are escalated immediately rather than saved for the report.
Reporting Built for Two Audiences
Every report contains an executive summary your board and customers can read, and a technical annex your engineers can action: reproduction steps, evidence, CVSS scoring, and specific remediation guidance. Reports are quality-assured before delivery and structured for auditors, insurers, and customer due diligence reviews.
Debrief & Free Retesting
A full debrief walks your team through findings and attack chains, in person in Derby or at our Leeds headquarters where practical, or by video call. Once you have remediated, we retest the fixed findings free of charge and issue updated reporting, so your evidence shows issues closed, not just found.
The best time to test your defences is now.
