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 Monitoring
Identity & Access
Project Management
Communication
Observability
Data & Analytics
Private AI
Each deployment includes architecture design, hardening, SSO integration, backups, upgrades and documentation, with ongoing support available after launch.
Plan a deploymentCompliance 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 trainingCan DeployOpen work inside our existing AWS/Azure environment?
Yes. We can adapt a self-hosted deployment to your existing AWS or Azure environment. We confirm the target platform, access boundaries and security requirements before scoping the work.
Do you support fully on-premise or air-gapped deployments?
Yes. We can plan private, on-premise and air-gapped deployments around your network and operating constraints. The deployment approach is agreed before implementation begins.
Can you customize open-source software, not just deploy it?
Yes. We deploy and customize open-source platforms around your workflows, infrastructure and security requirements, then document the setup so your team can operate it.
Do you provide ongoing support after deployment?
Yes. Support can continue after launch. We agree on the systems covered and how responsibilities are shared with your team before work starts.
Do you perform the formal SOC 2 / ISO certification audit?
No. We prepare your systems and evidence for assessment; we don't issue SOC 2 reports or ISO 27001 certifications. We can work alongside your independent auditor or certification body.
Can you work alongside our existing auditor or compliance platform?
Yes. We can work within your existing assessment process and compliance platform, focusing on the systems, controls and evidence your team needs to prepare.
What does a typical security testing engagement include?
We agree on scope and authorized targets first. Depending on the engagement, testing can cover applications, APIs, code, cloud and infrastructure, AI systems or attack scenarios, followed by findings and remediation guidance.
How are engagements priced?
Most engagements are fixed-scope and agreed before work starts. Ongoing support and continuous testing are available as retainers.
How long does an engagement take?
It depends on scope. You receive a plan with timelines during scoping.
How do you handle our data and credentials?
Access is limited to what the engagement requires, agreed in writing and removed when the work ends.
Can you work under our vendor terms?
Yes. We can review your security questionnaire, MSA and contract templates during scoping.
Can you sign an NDA before reviewing our environment?
Yes. Tell us you need an NDA before sharing sensitive technical or business details, and we'll arrange it first.
