Cyber security, incident response, and digital resilience.
Osiris helps your organisation reduce risk, respond quickly, and strengthen its security posture. We bring together certification, protection, monitoring, incident response, remediation, and digital forensics, all from one team you can rely on.
A complete cyber programme, not a list of tools.
Eight capabilities that turn cyber security from a compliance line into a genuine strength for your organisation. The right ones, sequenced the right way, and run by senior consultants.
Speak to a cyber specialistCyber Essentials
We handle your preparation, evidence, and certification through our IASME-accredited certification body. It is the control set most insurers and procurement teams now expect.
Explore Cyber EssentialsCyber Essentials Plus
A technical audit of your endpoints, patching, MFA, and access controls, giving independent assurance to your buyers, your regulators, and your board.
Discuss Cyber Essentials PlusCyber security audits
We show you where the gaps are, what they cost to close, and what to fix first, in a clear written report your board can act on rather than a tooling output.
Discuss security auditsIncident response
Containment, investigation, and recovery when your systems are compromised, with senior consultants on the call within the hour.
Discuss incident responseDigital forensics
Evidence preservation, technical analysis, and post-incident understanding that holds up in front of insurers, regulators, or a tribunal.
Discuss digital forensicsEndpoint and email security
Practical protection on the surfaces where most attacks actually land: EDR, email filtering, conditional access, and the operational discipline to keep them properly tuned.
Discuss managed protectionAwareness training
Short, sector-aware training your staff can complete, with phishing simulations that teach rather than punish, and reporting that maps to your insurance and Cyber Essentials evidence.
Discuss awareness trainingInsurance and compliance readiness
We help you get cyber insurance renewals over the line and map your controls to NCSC, ISO 27001, NHS DSPT, or your own framework, without unnecessary overhead.
Discuss assurance services
When your board sees cyber as operational risk, not just an IT line, the decisions get easier.
Cyber security stops being a debate about tooling the moment a leadership team understands it as an operational risk with a defined cost and a defined recovery time. Our job is to help you reach that conversation, with the evidence, the language, and the roadmap that let your board commit with confidence and your operations team get on and deliver.

Senior incident response on call, with containment, investigation, communications, and forensic discipline when it counts.
