Endpoint Detection and Response (EDR) replaces legacy antivirus with behavioural detection, ransomware rollback and one-click isolation on every laptop, desktop and server. ITSecOps deploys and manages EDR from Sophos, Microsoft, SentinelOne, CrowdStrike and Bitdefender. We partner with every industry-standard vendor, so you get the licence at partner pricing, cheaper than buying direct, with onboarding, policy tuning and support included.
Updated September 4, 2026. Research published in August 2026 found that around 80 percent of MITRE ATT&CK techniques used by current malware families are built to evade or disable endpoint tools. Signature antivirus does not survive that. EDR that records behaviour, and a team that reviews what it records, does.

What our EDR service includes
- Licence at partner pricing and provisioning under your tenant, with the product chosen for your platform and budget, not for our margin.
- Deployment through Intune, your RMM or our scripts, with removal of legacy antivirus and verification that every device reports in.
- Policy baseline: tamper protection, attack surface reduction, USB and application control, web protection, exclusions for line-of-business apps.
- Alert handling during business hours by our engineers, with an escalation path to you. Need after-hours coverage? Upgrade to MDR.
- Monthly health report: coverage gaps, unprotected devices, detections and recommendations.
Do you need EDR or MDR?
EDR alone is enough when your company has fewer than about 50 endpoints, no regulated data and an internal person who will act on alerts the same day. Move to MDR when any of these is true: 50 or more endpoints, HIPAA, NIS2, CMMC, ISO 27001 or SOC 2 obligations, a cyber insurance questionnaire that asks for 24/7 monitoring, or no one available at 02:00 on a Sunday. The Security Stack Recommender makes this decision for you from eight questions, and EDR vs MDR vs XDR explains the differences in depth.
EDR for MSPs
MSPs use ITSecOps to deploy and manage EDR across all their clients under the MSP’s brand, with multi-tenant consoles, per-client policies and a white-label helpdesk. See white-label MSP support.
Frequently asked questions
Do I still need antivirus with EDR?
No. Every product above includes next-generation antivirus. Running a second antivirus alongside EDR creates conflicts and slows machines, so we remove it during onboarding.
Which EDR is best for a Microsoft 365 company?
If you already pay for Microsoft 365 Business Premium, Defender for Business is included and is a strong starting point. Companies that want ransomware rollback, firewall integration or macOS depth usually choose Sophos or SentinelOne on top.
Does EDR cover servers and Linux?
Yes. All listed products protect Windows Server, and Sophos, SentinelOne, CrowdStrike and Bitdefender cover Linux. Server licences are priced slightly higher than workstation licences.
How long does deployment take?
Typically 3 to 7 business days for up to 200 devices, including legacy antivirus removal and policy tuning.
Can I switch vendors later?
Yes. Because we hold partnerships with every vendor above, migrating from one EDR to another is a project we run regularly, usually within one billing cycle.
