Know where you stand and what to fix first

Cybernet is an independent security consultancy. We test your systems and controls, explain the weaknesses we find in order of priority, and help your team fix them.

Our services

Web application & API testing

We test web applications and REST/GraphQL APIs with and without authentication, against the OWASP Top 10 and beyond. That covers business-logic flaws, broken access control and chained privilege escalation.

Mobile app testing

Static and dynamic analysis of iOS and Android apps, covering transport security, local storage and the backing API, which is usually where the real problem turns out to be.

Network testing

External perimeter and internal network testing. We map what you expose in practice, whatever the asset register says, and then show how far an attacker gets from each foothold.

Server testing

Linux and Windows servers, physical, virtual or in the cloud. We check what they expose, how they're patched and configured, and how far an attacker gets from an ordinary account.

Cloud security testing

For AWS, Azure and GCP, we analyse IAM policies, review what's publicly exposed, check logging and detection coverage, and look for drift from your own baseline.

Security consulting

Advice when there's nothing to test yet, or after a test: threat modelling, design and architecture reviews, secure development practices and help planning the fixes.

What you can expect

Independent advice
We don't resell anything. The consultant who scopes your engagement is the one who does the work.
A fixed price up front
Before we start, we agree the scope with you in writing and give you a fixed price and timeline.
Evidence for every finding
Each finding comes with the evidence behind it, its business impact and a fix your engineers can ship.
Support after the report
We support your team while it fixes what we found, and retest the fixes once they're in.

Ways to work with us

Project engagement

A fixed-price test with an agreed scope and clear start and end dates. A good fit for a release gate, a customer requirement or an annual assurance cycle.
  • Fixed price and timeline
  • Technical + executive report
  • Retest of your fixes
  • Remediation support

Security retainer

A block of consultant days you draw down over the year, with a named lead who already knows your estate. It suits you if your security work runs all year round.
  • Named lead consultant
  • Quarterly testing cycle
We scope every engagement individually. These are the usual arrangements, and the scoping call settles the details.

How to start

Choosing a service

Not sure which service fits?
We're happy to talk it through.

A penetration test shows what an attacker could do with an app, network, server or cloud estate you already run. Consulting is for the questions a test doesn't answer: how to design a system, which fixes to make first and how to stop the same problems coming back. If you're still not sure, describe what you have on the scoping call and we'll recommend one.

It depends on the scope. As a guide, a single web application or a small external perimeter takes about five testing days, an application with its API and infrastructure about ten, and several applications tested internally and externally twenty or more. After the scoping call you get a fixed quote, so you know the cost before we start.

A project suits one piece of work with a clear deadline, such as a release, a customer requirement or your annual assurance cycle. If security work comes up all year, a retainer makes more sense: you draw down consultant days as you need them, and your named lead already knows your estate. You can also start with a project and keep us on a retainer afterwards.

A test isn't always the right first step. If you're still designing the system, a threat modelling and architecture review catches design flaws before any code exists. If you don't know where your weak spots are, a short consulting engagement helps you decide what to test first.

Tell us what you've built and we'll suggest where to start.
