Three Ways to Work With Us
Most clients start with one and add another as they grow. Not sure which fits? We'll recommend on a discovery call.
A clearly-scoped engagement with milestones, timeline and a fixed price — ideal for migrations, new builds, modernisation or a security assessment.
- Written scope & milestones
- Fixed, itemised price
- Defined deliverables & handover
- Optional support add-on
A monthly partnership for teams that need their infrastructure monitored, secured and continuously improved — with SLAs you can hold us to.
- 24/7 monitoring & incident response
- Patching, backups & DR
- Continuous cost & security optimisation
- Defined SLAs & monthly reporting
Embed vetted senior engineers into your team, managed by you, for as long as you need them — no recruitment lead time, no long lock-in.
- Vetted cloud / DevOps / AI / security engineers
- Managed by your team
- Monthly, flexible commitment
- Ramp up or down as needed

Which Model Fits?
A quick comparison. Many clients combine them — for example a fixed-scope migration followed by a managed retainer.
| Criteria | Fixed-scope project | Managed retainer | Staff augmentation |
|---|---|---|---|
| Best for | A defined outcome: migration, build, assessment | Keeping systems healthy and secure over time | Adding capacity to your own team |
| How it's priced | Fixed price, billed by milestone | Monthly fee for an agreed scope and SLA | Monthly rate per engineer |
| Who directs the work | Radiatus, against an agreed scope | Radiatus, within the agreed service | Your team leads |
| Commitment | Project duration | Ongoing, with an agreed notice period | Monthly and flexible |
| Typical services | Cloud migration, VAPT, modernisation | Managed IT, managed SOC, SRE | Cloud, DevOps, AI & security engineers |
No surprises, no lock-in you don't choose
Every engagement starts with a free conversation. Where the scope isn't clear yet, we propose a short, low-cost discovery so we both understand the work before you commit to a full build. From there you get a written proposal with itemised costs, milestones and clear success criteria.
Cost is driven by scope and complexity — how many systems or environments are involved, the compliance requirements (for example ISO 27001 or HIPAA and SOC 2), and how much existing automation and documentation we can build on.
- Transparent, itemised proposals
- Milestone-based billing on projects
- Clear SLAs on managed retainers
- Full IP assignment to you
Pricing Questions
It depends on scope, complexity and timeline. After a short discovery call we provide a clear, itemised proposal with milestones — no hidden fees. Most engagements start with a fixed-scope discovery so you can commit with confidence.
Yes. Our managed retainer covers 24/7 monitoring, patching, backups, incident response and continuous optimisation with defined SLAs. Many clients pair a build project with a retainer to keep systems healthy afterwards.
Yes — staff augmentation embeds vetted cloud, DevOps, security or AI engineers into your team on a monthly basis, managed by you, with no long-term lock-in.
Radiatus is US-registered (Dover, Delaware) and serves clients globally. We can invoice in major currencies and work under a mutually agreed contract with clear deliverables and IP assignment to you.
Because two "cloud migrations" or "penetration tests" can differ hugely in size and risk. A published number would either be padded or wrong. Instead we scope your actual requirement and give you a written, itemised price before any commitment.
Mainly scope and complexity: the number of systems, environments or applications involved, compliance requirements, how much existing documentation and automation there is, and how quickly you need it delivered.
Some do. Our GRC platform has published plans on the GRC pricing page, and each of our other products lists its own pricing on its own site.
Yes. Many clients begin with a focused assessment — for example a security test, architecture review or cloud cost review — and decide on next steps once they have the findings.
