CREST-Accredited Penetration Testing
Find the weaknesses before attackers do.
Laneden is a UK offensive-security firm. Rigorous CREST-accredited testing, reports both your engineers and your board can act on — and a remediation retest to confirm your fixes, free where the assessment size allows.

Penetration Testing
Hands-on, CREST-accredited testing of your infrastructure and applications.
Threat Simulation
Real-world attack scenarios against your people and processes.
Gravitas
ProductAttack-surface intelligence: breach data, stealer logs and dark-web exposure, correlated in real time.

Why Laneden
CREST accredited
Our methodology, technical capability and ethics are independently assessed by CREST — not self-declared.
Free remediation retesting*
Fix what we found and we confirm it at no charge on most engagements — a remediation check that reissues your report, set out in your proposal rather than sprung on you later.
Reports for two audiences
An executive summary your board can read, and technical detail your engineers can replicate — in the same report.
Practitioners who build
We co-own and supply Gravitas. We live in breach data and attacker tooling every day, and it shows in how we test.
* Free remediation retesting applies to penetration testing engagements. It is subject to the size of the assessment and available for three months from delivery of your report. A web application test is typically covered; a large engagement — an internal test across hundreds of systems, for example — is scoped and quoted, and a full re-assessment is always chargeable.
Assessed by CREST, not self-declared.
CREST accreditation means our methodology, technical capability and ethical standards were examined against the international standard for offensive security — and are re-examined to keep it. It is the difference between a firm that says it tests properly and one that has had to prove it.
What clients say
Independently collected — 4.8/5 from 21 reviews on Reviews.io, and 4.4/5 from 12 on Trustpilot (as at August 2026).

How an engagement runs
One methodology, applied the same way every time.
Every engagement runs the same six phases — scoped with you, executed by a named tester, and written up so both audiences get what they need. It is the method CREST assessed, and the same one set out in your proposal and your report.
Threat Model Development
We agree what the exercise is replicating: the credible threats to your organisation, the starting position, the objectives, and which controls are in scope. It is also where disruption is bounded, so the test does not cost you a working day.
Information Gathering
Enumerating the systems and services actually in play from that starting point, so the attack surface is mapped as it is rather than as the asset register describes it — and choosing tools and techniques that suit it.
Vulnerability Identification
Examining that surface for weakness, using automated tooling for breadth and manual technique for everything a scanner cannot reason about. Neither finds what the other does, which is why the blend is deliberate.
Attack Vector Development
Weighing each weakness against your actual environment — how exploitable it really is, what skill it demands, what it would cost you. The output is the routes that are practical here, not the ones theoretically possible somewhere.
Exploitation
Where it is appropriate, we exploit, which usually opens a fresh attack surface and sends us back round the cycle. Where exploiting would cause harm we verify the finding is genuine rather than a stale banner, and assume the worst case.
Reporting
One document for two audiences: an executive summary your board can act on, and the technical chain your engineers can reproduce step by step, each finding carrying its severity and its remediation.
Service Engagement Document
Methodology, approach and NDA — agreed before any work starts.
Proposal
Scope, deliverables and a single total price for the agreed scope — not an open-ended day-rate engagement.
Authorisation Form
Formal written consent, so testing is always lawful and in-scope.
A scoped proposal within two working days, carrying a single total price for the agreed scope — not an open-ended day-rate engagement.
