Offensive security
Find out what an attacker would find. First.
Redstackd is an offensive security company. We test your applications, networks, people and buildings the way a real attacker would, then help you fix what we find.
Penetration testing
Find the weaknesses in your applications, networks and perimeter before someone else does.
Web application testing
Manual testing of web apps and APIs against OWASP and beyond.
External penetration testing
Test your internet-facing perimeter, remote access and cloud exposure.
Internal network testing
Assume breach. See how far an attacker could move inside your network.
Vulnerability scanning
Scheduled scans with results reviewed and prioritised by a human.
Adversary simulation
Test people, processes and buildings the way a determined attacker would.
Red teaming
Objective-led attack simulation that tests your detection and response.
Phishing campaigns
Realistic phishing simulations with clear, blame-free reporting.
Social engineering
Phone, SMS and in-person pretexting against your people and processes.
Physical assessments
Authorised attempts to get into your buildings and onto your network.
How we work
Senior-led
The person who scopes your test is the experienced tester who does it. Nothing is handed off to a junior or run through a scanner and sent on.
Fixed pricing
A short scoping call, then a fixed quote. No day-rate surprises, and the debrief and retest are included.
Reports people read
A plain-English summary for leadership, and evidence and clear fixes for every finding so your team can act on it straight away.
Retest included
We retest critical, high and medium findings within 90 days of the report at no extra cost, and give you an updated report.
For managed service providers
Add offensive security to your stack, under your brand.
White-label penetration testing, phishing and red teaming that you resell at your own margin, while you keep the client relationship.
The Redstackd newsletter
One short email a month: the attacks we are seeing, the findings that keep coming up and what to fix first. No sales pitches.
