A breach always costs more than prevention
We embed security thinking at every stage of development. From threat modelling to penetration testing and compliance readiness, we build the posture that protects your users, your data, and your reputation.
Atomic’s best practice design principles and first class technical expertise has been instrumental in building HALO into the award winning app it is.

Halo Solutions

Over 70,000 downloads in its first week, a 15% uplift in bookings, and No.1 in the travel app charts. We designed a native iOS and Android app that made it simpler for Center Parcs guests to plan, book, and get the most from their stay.
Atomic's cyber security team works with ambitious brands to build secure-by-design systems, identify vulnerabilities before they're exploited, and maintain the security posture their business requires.
Cyber security in software development means designing, building, and testing software with security as a core requirement, not an afterthought. We call it security by design.
Penetration testing is a simulated cyber attack on your software or infrastructure, conducted by specialists to identify exploitable vulnerabilities before malicious actors can find them.
Threat modelling is a structured process of identifying potential security threats to your system, assessing their likelihood and impact, and determining the controls needed to mitigate them.
Through security requirements at the design stage, code review with security focus, static analysis tools, and structured testing at every major milestone, not just at the end.
We work with OWASP, ISO 27001, Cyber Essentials, and NCSC guidance, applying the standards most relevant to your product, industry, and the sensitivity of the data you handle.
At minimum annually, and after any significant architecture change or major feature release. For regulated industries or high-risk applications, more frequent testing is advisable.
Cyber security investment varies by scope, product complexity, and testing depth. We scope every engagement individually and give a clear estimate after understanding your security posture.
A vulnerability assessment identifies and classifies potential weaknesses. A penetration test goes further, actively attempting to exploit those weaknesses to understand real-world risk.
A clear scope of what's to be assessed, access to relevant environments, and any existing security documentation. We'll agree rules of engagement before any testing begins.
Yes. We regularly assess third-party software. We begin with a technical review before scoping the assessment to ensure it covers the most relevant attack surfaces for your product.
