Guides for people who buy security testing

No news and no opinions about the threat landscape. Practical answers to the questions clients ask before, during and after an engagement.

    How to prepare for a penetration test

    A checklist for the client: what to decide, what to prepare and whom to tell before the testers start, so that paid days are spent on testing.

    How to read a CVSS 4.0 score

    What the number and the vector in a finding mean, which metrics they are built from, and why a score of 9.3 is not yet a priority.

    Penetration test, bug bounty or red team: how to choose

    Three ways to have your security tested answer three different questions. A guide to choosing by the question you need answered, not by the name of the service.

    Prompt injection is a permissions problem

    A language model cannot reliably tell instructions from data. The damage of an injection is decided by what the application around the model is permitted to do.

    A stranger reported a vulnerability: a response plan

    An email arrives from someone you do not know: they found a vulnerability in your product. What to do in the first hour, the first day and the first week.

    What makes a penetration test legal

    The same actions are a service with authorisation and an offence without it. Which documents create the authorisation, who may sign them, and where the usual gaps are.

Free check

We check your website free of charge

If we find no problems, you receive the report free of charge as well. You pay for the report only when we find problems, and its price depends on their number and severity.

Application security

Free website security check

We look at your website from the outside, the way an attacker does, and check whether it can be broken into: weak settings, outdated software, exposed files, unsafe forms. The check is free of charge.

More about the service

Application security

Web application penetration testing

We try to break into your web application the way a real attacker would: log in to the accounts of other people, read the data of other customers, change prices or orders. You learn what is possible before criminals do.

More about the service

Application security

API security testing

An API is the channel through which your app, your website and your partners exchange data with your servers. We check that nobody can use it to read or change data that is not theirs.

More about the service

Application security

Mobile application penetration testing

We examine your iOS or Android app and the servers behind it: what the app keeps on the phone, what can be extracted from it and whether its requests can be tampered with.

Application security

Secure code review

Our specialists read the source code of your product and find the mistakes that lead to a break-in, including those that cannot be seen from the outside.

More about the service

Infrastructure and cloud

Cloud & Kubernetes security assessment

We check how your cloud is set up (AWS, Azure, Google Cloud, Kubernetes): who has access to what, which data is open to the internet and how far an attacker gets after the first mistake.

More about the service

Infrastructure and cloud

Infrastructure penetration testing

We test your servers and your office network from the outside and from the inside: can an attacker get in, and once inside, reach the accounting system, the mail or the backups.

More about the service

Infrastructure and cloud

External attack surface assessment

We find everything your company exposes to the internet, including what has been forgotten: old websites, test servers, leaked passwords. Then we show which of it can be attacked.

More about the service

Infrastructure and cloud

CI/CD & supply chain security

We check the path your code takes from the developer to the customer: build servers, third-party libraries, access keys. Whoever controls that path controls your product.

More about the service

Adversary simulation

Red team operations

A full-scale exercise. Our team plays a real attacker with a goal, for example to reach customer data, and you see whether your defence notices and stops it.

More about the service

Adversary simulation

Purple team exercises

Our attackers and your defenders work side by side: we show an attack technique, your team checks whether it sees it, and the gaps in monitoring are closed on the spot.

More about the service

Adversary simulation

Social engineering assessment

We test people, not machines: the phishing emails, calls and messages that attackers use to obtain passwords. You learn how many employees would be deceived and what to train.

More about the service

AI, Web3 and cryptography

AI & LLM security testing

If your product has a chatbot or another AI model, we check whether it can be talked into revealing confidential data, breaking its own rules or acting on behalf of someone else.

AI, Web3 and cryptography

Smart contract audit

Before a smart contract holds money, we look for mistakes in its code that would let someone withdraw or freeze the funds. After deployment such mistakes cannot be corrected.

More about the service

AI, Web3 and cryptography

Cryptography review

We check how your product encrypts data and protects keys: whether the right algorithms are chosen and whether they are applied correctly. A mistake here makes the encryption useless.

More about the service

Programs and assurance

Bug bounty program management

A bug bounty is a program in which independent researchers look for vulnerabilities in your product and are paid for each one they find. We launch and run such a program for you.

More about the service

Programs and assurance

Vulnerability disclosure program (VDP)

A public page and a procedure that tell researchers how to report a vulnerability to you safely. Without them reports get lost or arrive as threats. We set the process up and handle incoming reports.

More about the service

Programs and assurance

Continuous penetration testing

Instead of one test a year, we test every significant change of your product throughout the year, so that a new vulnerability does not wait for months to be found.

More about the service

Programs and assurance

Compliance-driven penetration testing

A penetration test arranged so that an auditor, a regulator or a large customer accepts its report: PCI DSS, DORA, NIS2, ISO/IEC 27001, SOC 2.
