Secure your AI agents.
We test AI agents, MCP servers and LLM applications for prompt injection, tool misuse and data exposure, based on the OWASP Top 10 for Agentic Applications.
Open software. Deployed for your enterprise.
We deploy, secure and support self-hosted open-source platforms inside your infrastructure.
Data ownership
Platforms run in your cloud account, data center or private network. You decide where data is stored and who can access it.
Predictable cost
Costs are based on infrastructure and support rather than per-user licences, which keeps them steady as more teams adopt a platform.
Auditable security
Open code, hardened configuration and SSO. Your security team can review each component and use it as evidence for SOC 2, ISO 27001 and other audits.
Flexibility
Open standards and documented deployments. You can extend a platform, run it in-house or change support providers at any time.
Platforms we deploy and support
Security & Identity
Business & Finance
Data, AI & Integration
Digital Workplace
Compliance for modern companies.
We prepare organizations for SOC 2, ISO 27001, PCI DSS, HIPAA, DORA, NIS2 and other frameworks. Our readiness work covers the systems, controls and evidence behind your compliance program, so your team knows where it stands before the formal assessment.
We prepare your organization for assessment. Certification is issued by your independent auditor, and we can work alongside them and your compliance platform.
Audit planning
Define the audit boundary, applicable systems, control owners, timelines, and evidence requirements before the assessment begins.
Access control & identity
Review user access, MFA, privileged accounts, role permissions, and joiner, mover, and leaver processes.
Third-party vendor risk
Assess critical vendors, data access, security reviews, contracts, dependencies, and ongoing vendor oversight.
Vulnerability management
Review scanning, patching, remediation timelines, penetration test findings, and how security issues are tracked to closure.
Incident response
Assess detection, escalation, response procedures, breach handling, communications, and incident records.
Control testing & evidence
Test whether controls are operating as expected and verify that supporting evidence is complete and ready for auditor review.
See how your systems hold up under attack.
Penetration testing and security assessments for applications, cloud infrastructure, AI systems and people, with clear findings and remediation guidance.
Cloud & infrastructure testing
Cloud accounts, networks, wireless systems and connected infrastructure.
Each engagement includes an agreed scope, findings rated by severity, executive and technical reports, and a retest after fixes.
Train your team for the worst.
Private cyber ranges modelled on your infrastructure and tools, for SOC, incident response and security teams to practise detection and response.
- Your environment: scenarios use the systems, logs and tools your team works with.
- Private deployment: ranges run in your cloud, on-premises or hosted by us.
- Debrief after each exercise: a review of detection, response and areas to improve.
Built for industries where security matters.
DeployOpen works with organizations operating sensitive systems, regulated infrastructure and high-value data. Our work adapts to the technical, security and compliance requirements of each environment.

Team trainingHow are engagements priced and scheduled?
Most engagements are fixed-scope. We agree on scope, deliverables and timelines in writing before work starts. Ongoing support and continuous testing are available as retainers.
Can you work in our cloud, on-premises or air-gapped?
Yes. We work in your AWS, Azure or Google Cloud accounts, in your own data centers and in air-gapped networks. We confirm access boundaries and security requirements during scoping.
Do you issue SOC 2 reports or ISO 27001 certificates?
No. Those are issued by your independent auditor or certification body. We prepare your systems, controls and evidence, and work alongside your auditor and compliance platform.
Can you sign an NDA and work under our vendor terms?
Yes. We can sign an NDA before you share sensitive details and review your security questionnaire, MSA and contract templates during scoping.
How do you handle our data and system access?
Access is limited to what the engagement requires, agreed in writing and removed when the work ends.
Can our team run what you deploy?
Yes. We customize each platform around your workflows, document the setup and train your team to operate it. Ongoing support is available if you want it.
