IT & Security for Professional Services

Managed IT that protects client data, keeps billable staff productive, and removes the daily IT friction that eats into margins.

Every hour your team spends troubleshooting IT is an hour not billed to a client. Every password reset, every VPN issue, every printer jam: it all comes off your margin.

Professional services firms sell expertise and time. When IT friction eats into both, the cost is not just frustration. It is revenue. You need IT that enables billable work, not competes with it. And increasingly, you need security that your clients can verify.

Sound familiar?

These are the challenges we hear from professional services firms every week.

Every hour your team spends on IT issues is an hour not billed to clients

Client data security is a competitive requirement, not just a compliance checkbox

Staff expect seamless remote working but your current setup creates friction

You have grown past the point where the 'IT person who also does other things' approach works

Onboarding new hires takes days instead of hours

How we help

Our COSAINT model gives professional services firms a managed IT partner that handles everything from security to helpdesk – so your team can focus on client work. Every tier includes the enterprise security baseline, with additional layers of support as your firm grows.

Professional services clients typically start with COSAINT Managed, which covers full helpdesk support, user onboarding and offboarding, M365 administration, and our complete security stack. Firms with on-premises infrastructure or complex compliance requirements may find COSAINT Complete a better fit. Either way, we will help you identify the right starting point.

Professional Services IT FAQ

How quickly can you onboard new staff?
We typically complete user provisioning within 2 hours of receiving the request, including Microsoft 365 account creation, security group membership, device enrolment, MFA setup, and application deployment. For planned hires, we can have everything ready on day one so new staff are productive from their first morning.
Can you support staff working from client sites?
Yes. Our cloud-first approach means your staff can access all company resources from any managed device, regardless of location. We use conditional access and Intune compliance policies instead of traditional VPN, so access works seamlessly from client networks, co-working spaces, or home offices.
How do you handle the transition from our current IT provider?
We manage the full transition with minimal disruption. This includes parallel running during the handover period, DNS and domain migration, user communication and training, and a structured first 90 days programme that establishes the security baseline and knowledge base.
What happens when a staff member leaves the firm?
We execute a documented offboarding process that revokes access within the agreed timeframe, typically within 1 hour for immediate departures. This includes disabling the Microsoft 365 account, revoking device access, transferring mailbox and OneDrive data to the designated manager, and removing the user from all security groups and applications.
What COSAINT tier is right for our professional services firm?
Most professional services firms start with COSAINT Managed. This tier covers the full security baseline, helpdesk support, user lifecycle management, Microsoft 365 administration, and device management. If your firm has on-premises servers or complex network infrastructure, COSAINT Complete adds the infrastructure management layer.
