DevSecOps & Secure Development

Build security into how you write, review, build and release software, without slowing your teams down.

Most vulnerabilities we find in penetration tests started as a line of code, a library or a pipeline setting. Finding them at the end of a project is expensive; preventing them, or catching them early, is far cheaper and far less disruptive.

Samurai Security helps development teams build security into the software lifecycle. We review your code and your CI/CD pipelines, train your developers in secure coding, and test your web applications and APIs on a schedule that fits your release cycle. After every review or test, we talk your team through the findings so the fixes stick.

What Is DevSecOps?

DevSecOps means making security part of everyday development and operations rather than a gate at the end. Security checks run in the pipeline, developers know how to avoid common flaws, code is reviewed with security in mind, and testing keeps pace with frequent releases.

Our role is to give you an independent, expert view of where your software and delivery process stand today, fix what matters most, and help your teams keep it that way.

Why Secure Your Development Process?

Modern applications are released often, rely heavily on open-source packages and are built and deployed by automated pipelines that hold powerful credentials. Each of those is a route for an attacker: a vulnerable dependency, a leaked secret in a repository, a pipeline that can be tampered with, or a change that ships without review.

Securing the development process reduces the number of vulnerabilities that reach production, shortens the time to fix the ones that do, and gives customers and auditors evidence that security is designed in.

Our DevSecOps Services

Secure code review

Manual review of your source code by experienced consultants, supported by tooling, focusing on authentication, authorisation, input handling, cryptography, secrets and business logic. Reviews can cover a whole application or the high-risk areas and recent changes.

CI/CD pipeline security review

A review of your build and release pipelines and source control, such as GitHub, GitLab, Azure DevOps or Jenkins, covering access controls, branch protection, secrets management, build integrity, dependency and container scanning, and deployment permissions.

Security tooling in the pipeline

Advice on adding and tuning automated checks, such as static analysis (SAST), software composition analysis (SCA), secrets scanning, infrastructure-as-code and container scanning, so they find real issues without flooding developers with noise.

Testing that fits your release cycle

Web application and API penetration testing scheduled around your releases, from a test before a major launch to regular testing of new features, so security keeps pace with development.

Secure code training for developers

Practical training that shows your developers how common vulnerabilities are exploited and how to prevent them in the languages and frameworks they use.

Report debrief and remediation support

After every review or test, we talk your developers through the findings, explain the root causes and agree practical fixes, and can re-verify them once they are in place.

Our Approach

01

Discovery

We learn how your teams build and release software: languages and frameworks, repositories, pipelines, environments and release frequency, and where your biggest risks lie.

02

Proposal

We recommend the mix of code review, pipeline review, testing and training that will make the most difference, with a clear scope, timings and cost at £1,350 per consultant day.

03

Review and testing

Our consultants carry out the agreed reviews and tests, working with your developers and keeping disruption to a minimum.

04

Report and debrief

You receive a prioritised report with evidence and remediation guidance for each finding, and we talk your team through it in a debrief.

05

Ongoing support

We can retest fixes, run training and schedule testing around future releases. Retesting is scoped to the number of findings to re-verify and quoted up front.

Why Choose Samurai Security?

Testers who know how code fails

Our CREST-accredited consultants find vulnerabilities in applications every day, and bring that attacker's view to code and pipeline reviews.

01

Practical, developer-friendly advice

We explain findings in terms developers can act on, with root causes and fixes rather than just scanner output.

02

Joined-up service

Code review, pipeline review, application and API testing and developer training from one team, so lessons from testing feed straight back into how you build.

Client Testimonials

“Samurai takes the time to understand our needs and helps us to be an enabler for Flagship Group’s mission. It’s always a pleasure to work with them and I’d recommend them to others.”

“We were astonished by what Samurai’s Black Dragon assessment revealed, even though we thought we had everything covered. The findings spoke for themselves, and the team’s expertise and clarity were outstanding.”

"Samurai’s Black Dragon: Attack Surface Risk Assessment was exactly what we needed and something we’ve never seen done before. They turned it around quickly, highlighted risks that could have easily been overlooked, and gave us a clear roadmap for improvement."

Frequently Asked Questions

What is the difference between secure code review and penetration testing?

A penetration test attacks the running application from the outside, as an attacker would. A secure code review reads the source code to find flaws directly, including issues that are hard to reach through testing. They complement each other, and many teams use both.

Can you work with our existing pipeline and tools?

Yes. We review the pipeline and tooling you already use, such as GitHub, GitLab, Azure DevOps or Jenkins, and recommend improvements rather than asking you to start again.

How do you fit testing around frequent releases?

We agree a testing schedule with you, for example testing before major releases and periodic testing of new features and APIs, so security keeps pace without holding up delivery.

Do you offer secure coding training?

Yes. Our secure code training shows developers how vulnerabilities are exploited and how to prevent them, and can be tailored to your languages, frameworks and the findings from your own tests.
