Offensive security,
driven by code.
We read your source, chain the bugs that matter into working exploits, and show you exactly what an attacker could do with them. No theoretical findings, no report padding. If it can't be part of an exploitable chain, we're not interested. CREST accredited. Source code never trained on, always deleted.
Why Realize Security?
Offensive security specialists who prove impact, not just presence.
Exploits, not findings
Every engagement starts in your source code and ends in proof: working exploits and PoCs that chain individual bugs into real impact. If it can't be exploited, it doesn't make the report.
Custom tooling, real tradecraft
We build the tooling, infrastructure and offensive solutions each target needs, the way a motivated attacker would. Off-the-shelf scanners don't find chains.
Expert, accountable, accredited
Every engagement is led by an expert operator backed by CREST accreditation. UK-based. Your source code is never used to train AI models, and is securely deleted on completion.
Services
ExploreRed and Purple Teaming
Adversary simulation that tests your detection and response, not just your controls. Covert red team operations and collaborative purple team exercises.
ExploreApplication Penetration Testing
Web, API and mobile. We read the source, build the exploit, and prove the impact. CREST accredited.
ExploreCloud Security
Cloud penetration testing that chains identity, network and workload weaknesses into real access paths. CREST accredited.
ExploreNetworks and Infrastructure
External and internal infrastructure testing that follows the attack path from exposed service to domain compromise.
ExploreCode Review-Led Pentest
Source-first application testing. We read the code, build the exploits, and chain them into demonstrable impact. Web, API, and mobile.
ExploreAppSec Diagnostic
A fixed-scope, source-led assessment of a single application. Exploitable findings prioritised by impact, with a clear readout of where you stand.
ExploreSupply Chain Security
Dependencies, build pipelines, and third-party integrations attacked the way an adversary would: as a route into your code and your environment.
ExploreThreat Modelling
Find the attack paths before we, or anyone else, exploit them. Know what to focus on, what to prioritise, and where to invest.
ExploreAppSec Partner Retainer
Offensive security as an extension of your engineering team. Code review, exploit development, pentesting, and threat modelling on call.
Accreditation and Trust
CREST approved and independently assessed to ensure the highest standards of service quality and information security.
How we engage
Every engagement follows a clear, repeatable process. No surprises, no ambiguity.
Scoping call
We meet with business and technical stakeholders to understand the target, its attack surface, and what a real compromise would look like for you.
Proposal
A written proposal covering scope, approach, timeline, and a fixed-fee quote tailored to your engagement.
Statement of Work
Clear deliverables, timelines, and terms agreed before any work begins. No ambiguity.
Kickoff
NDA signed, secure source code transfer where applicable, environment and infrastructure access arranged. Testing begins.
Delivery
Report built around exploit chains: executive summary, a technical walkthrough of each PoC, and code-level remediation guidance. Debrief call to walk through everything.
Handover
Source code securely deleted. Deletion certificate provided. Ongoing support available via retainer.
