Secure Software Development

Produce and deploy better quality and secure software, faster.

Your challenges

Organised cybercrime is becoming a multi £trillion industry, stringent regulations are being introduced around the globe and users have an inherent expectation for secure and private software. This change in landscape means that responsibilities have shifted towards software organisations becoming more ethical and accountable for their products, in order to avoid substantial financial and reputational implications.

The cost of removing an application security vulnerability during the design phase ranges from 30-60 times less than if removed during production.

Our solution

Introducing a Secure Software Development Lifecycle (SSDLC) is the way for you to focus on ‘Secure by Design’, allowing a ‘shift left’ approach, which enables the production and deployment of better quality and secure software, faster. Deploying a SDLC will enable you to retain user trust, operate in new markets and comply with regulations, such as the General Data Protection Regulation. We help you achieve and champion a DevSecOps approach and satisfy security compliance objectives for PCI DSS, SOC2, and other common requirements.

Deploying insecure code is no longer an option.
