Complete IT Services for Mid-Sized Business Needs

Security-first management and support

Managed IT

Reliable Daily Operations

Mid-sized teams need continuous oversight without adding internal headcount. Perimetra monitors systems, manages infrastructure, coordinates vendors, and keeps endpoints updated so small issues are handled before they interrupt billable work or patient and client service.

You get patch management, system maintenance, technology lifecycle guidance, and clear reporting that shows what was reviewed, what changed, and what still needs attention.

Cybersecurity

Security Built Into IT

Security is built into the service, not treated as an add-on. Perimetra reviews your endpoints, email providers, and existing tools, then aligns protection around ransomware prevention, phishing reduction, vulnerability management, and incident response planning.

Behavioral AI threat detection and daily model updates support practical monitoring, while monthly reporting gives you proof of activity and a clearer picture of risk exposure.

Helpdesk Support

Fast User Assistance

When staff cannot log in, access software, connect devices, or resolve an error, productivity slows quickly. Perimetra provides end-user support, ticket management, password assistance, hardware support, account administration, and user onboarding support.

The goal is direct issue resolution with plain-language communication, so users know what is happening, what was fixed, and when to expect the next step.

Cloud Services

Managed Cloud Stability

Cloud environments need active management to stay secure, efficient, and aligned with your business. Perimetra supports cloud migrations, Microsoft 365 management, hybrid cloud environments, backup solutions, and cloud security configuration.

You get help modernizing infrastructure without unnecessary disruption, plus practical optimization guidance that reduces tool sprawl and keeps your team working from dependable, well-managed systems.

Risk Management

Clear Risk Visibility

Mid-sized businesses often face insurance, audit, and client requirements without a large internal compliance team. Perimetra provides risk assessments, compliance assessments, security reviews, policy development, governance guidance, and audit preparation support.

The focus is clarity: identify gaps, document controls, prioritize remediation, and maintain practical evidence that helps leadership understand progress over time.

Continuity Planning

Resilient Recovery Plans

Downtime planning matters before an outage happens. Perimetra helps protect operations through backup management, disaster recovery planning, business continuity planning, recovery testing, documentation, and infrastructure resilience support.

Your business gets a clearer recovery path, better data protection, and practical testing that confirms whether critical systems can be restored when timing matters most.

You get a dedicated partnership built for SMB reality: fast deployment, clear communication, measurable support, and strategic guidance without unnecessary bureaucracy.

A Practical Operating Model for Growing Teams

Support is delivered through practical channels, with AI virtual support available 24/7 and cyber and systems engineers guiding remediation. For urgent active-client issues, Perimetra aligns to a P1 response SLA under 2 hours.

The result is a quieter IT environment with stronger visibility: fewer surprises, faster issue handling, clearer reports, and a technology roadmap that supports growth instead of slowing it down.
