Managed Detection and Response Built for Real Firms

Practical monitoring, faster response

Endpoint Monitoring

Spot threats sooner

MDR starts with visibility across the systems your firm relies on every day. Perimetra reviews endpoints, security tools, and key activity patterns to identify where suspicious behavior may be missed.

Alerts are managed with context, so your team is not buried in noise. The outcome is a clearer view of active risk, stronger endpoint protection, and monitoring that supports faster action when something looks abnormal.

Email Security

Protect trusted inboxes

Many incidents begin in the inbox. Perimetra helps reduce phishing, business email compromise, and suspicious account activity through managed email security review, alert handling, and response coordination.

The focus is practical: identify risky messages, support account protection, and help your team understand what happened. This gives law, medical, and accounting firms stronger protection around the communication channels clients trust most.

Alert Investigation

Respond with clarity

Not every alert deserves the same response. Perimetra investigates suspicious activity, reviews context, and helps separate routine events from issues that need immediate attention.

When action is required, you receive clear guidance on containment, remediation, and next steps. This keeps your team focused on operations while cyber and systems engineers help move the issue from detection to resolution with less delay.

Risk Remediation

Reduce exposed gaps

MDR is stronger when it also shows what needs to improve. Perimetra connects threat detection with vulnerability management, risk reviews, and practical remediation steps that fit your environment.

You get visibility into weak points across endpoints, configurations, and security processes. Instead of a long technical checklist, you receive prioritized guidance that helps reduce exposure, support insurance conversations, and improve security over time.

Threat Reporting

See proof in reports

Security decisions are easier when reporting is direct and understandable. Perimetra provides monthly threat reports that show what was monitored, what was detected, what was addressed, and what should happen next.

This approach reflects radical transparency: clear metrics, honest findings, and proof in every report. Business leaders can see progress without needing to decode technical logs or wait for a crisis to understand risk.

Fast Onboarding

Deploy with less friction

Deployment should not take months or drain internal resources. Perimetra handles onboarding, setup support, agent deployment, dashboard configuration, and partner portal access with a focus on speed over bureaucracy.

Most deployments can happen quickly depending on client size, with 48-hour deployment available. Your team gets managed protection with minimal disruption, plus ongoing support through practical channels when help is needed.

Security Monitoring That Turns Risk Into Action

Managed Detection and Response gives your firm practical protection without forcing your team to become security analysts. Perimetra reviews endpoints, email systems, current tools, and risk exposure, then turns that information into a clear plan.

Once deployed, monitoring runs quietly in the background while alerts are reviewed, investigated, and escalated when action is needed. You receive plain-language reporting, practical remediation steps, and proof in every report, so decisions are based on evidence instead of guesswork.

The goal is simple: faster detection, clearer response, and security operations built for SMB reality.

What MDR Covers for Your Day-to-Day Operations

MDR should make security easier to manage, not harder. Perimetra focuses on fast setup, transparent reporting, and response support that fits the way law firms, medical practices, and accounting teams actually work.

Endpoint activity monitored for suspicious behavior
Email security support for phishing and BEC exposure
Alert triage to separate noise from priority issues
Incident investigation with practical remediation guidance
Monthly threat reports that show what happened and what improved
Deployment support designed to minimize disruption

You get visibility, action, and a dedicated partner without enterprise-level complexity.

Enterprise-Level Awareness Without Enterprise Complexity

Small firms often face the same ransomware, phishing, and endpoint risks as larger organizations, but without the same internal security staff. Perimetra closes that gap with managed detection, response coordination, and clear security guidance.

The process starts with discovery: endpoints, email providers, existing controls, and known gaps. From there, Perimetra deploys, configures, monitors, and reports with speed over bureaucracy. Daily AI model updates support behavioral detection, while cyber and systems engineers help translate alerts into next steps.

You are not left guessing what happened, what matters, or what to fix next.
