Endpoint protection software and the EDR dividing line

What to look for, and what to ignore

What Endpoint Protection Software actually costs

Endpoint protection pricing is deliberately opaque. Most enterprise vendors require a sales call to get a number, and the gap between entry-level and fully loaded pricing can be 5x or more. The market broadly splits into per-endpoint annual pricing (dominant model) and per-user monthly pricing (Microsoft ecosystem). Volume discounts are significant. A 5,000-endpoint deal often pays 40-60% less per endpoint than a 100-endpoint deal. What follows comes from the pricing vendors publish, and says plainly where a vendor publishes nothing at all.

For a mid-market organization protecting 500 endpoints, expect to spend $15,000-$90,000 per year on endpoint protection depending on your requirements. The low end gets you solid NGAV + basic EDR from Sophos, Bitdefender, or ESET. The mid-range ($40,000-$60,000) gets you CrowdStrike Falcon Pro or SentinelOne Control with full EDR. The high end gets you enterprise EDR with managed detection and response. If your organization has Microsoft 365 E5 licenses, Defender for Endpoint Plan 2 is included. Start there before buying a separate platform. For MSPs, Huntress at $8.99/endpoint/month is the standout value for fully managed EDR that does not require your technicians to be security analysts.

How to compare them

Detection efficacy against real-world attack techniques

The entire point of endpoint protection is stopping threats. Vendor marketing claims are meaningless. What matters is how the platform performs against attack techniques used in the wild, particularly fileless attacks, living-off-the-land techniques, and credential theft.

Ask: Request the vendor's most recent MITRE Engenuity ATT&CK evaluation results. Run a controlled red team simulation (using Atomic Red Team or similar) during the POC and measure detection rates. If a vendor discourages testing, that tells you everything.

False positive rate and tuning flexibility

An EDR platform that generates hundreds of false positives per week is worse than useless. It trains your team to ignore alerts, which means real threats get buried in noise. The best platforms produce low false positive rates out of the box and offer granular exclusion and tuning capabilities.

Ask: During the POC, track every alert generated and calculate the false positive rate. Ask the vendor how exclusions work. Can you exclude by process, path, hash, certificate, command line arguments, or a combination? How quickly can you create and deploy exclusions?

Agent performance impact on endpoint resources

The endpoint protection agent runs on every machine, all the time. If it consumes excessive CPU during scans, spikes memory during updates, or slows disk I/O during telemetry collection, your end users will notice and complain. You will face pressure to disable protections.

Ask: Deploy the agent on your oldest, most resource-constrained hardware during the POC. Measure CPU, memory, and disk I/O during idle, during a full scan, and during an active detection event. Compare against your existing endpoint security tool.

Investigation and threat hunting workflow quality

Detection is only step one. When an alert fires, your analysts need to investigate, understanding the full attack chain from initial access to current state. The investigation workflow determines how quickly your team can triage, scope, and respond to incidents.

Ask: Ask your SOC analysts to investigate a simulated incident during the POC. How many clicks does it take to get from an alert to the full process tree? Can analysts pivot from a suspicious process to all endpoints where that process has run? Is there a query language for threat hunting?

Managed detection and response (MDR) service quality

If you are considering the vendor's MDR offering, evaluate the humans behind the service as closely as the technology. MDR quality varies enormously. Some vendors provide genuine 24/7 expert monitoring and response, while others offer glorified alert forwarding.

Ask: What are the MDR team's mean time to detect and mean time to respond SLAs? Will the MDR team actively contain threats (isolate endpoints, kill processes) or only notify you? How does the MDR team communicate during an active incident: phone, Slack, email?

Total cost of ownership across the full stack

The per-endpoint license price is the starting point, not the final number. Module add-ons, data retention upgrades, premium support, professional services, and SIEM ingestion costs can double or triple the effective per-endpoint cost.

Ask: Ask the vendor for a full TCO estimate that includes: base license, all modules you plan to use, data retention for your required period, premium support if needed, professional services for deployment, and ongoing support costs. Compare vendors on TCO, not license price.

Before you buy

1. 1Inventory your endpoint fleet by OS (Windows, macOS, Linux), type (workstation, server, virtual machine, container), and location (on-premises, remote, cloud). This determines which platforms can provide adequate cross-platform coverage.
2. 2Determine whether you need self-managed EDR or managed detection and response (MDR). If you do not have dedicated security analysts who will monitor and investigate alerts 24/7, you need MDR. That changes the vendor field significantly.
3. 3Check whether you have Microsoft 365 E5 licenses. If so, you already have Defender for Endpoint Plan 2 included. Evaluate whether it meets your needs before purchasing a separate platform.
4. 4Review your cyber insurance policy requirements. Many insurers now require named EDR products, specific detection capabilities, and MDR services. Confirm that your chosen platform satisfies your insurer's requirements before purchase.
5. 5Define your data retention requirements for compliance and forensic investigation. Default retention periods (7-30 days) may not be sufficient. Extended retention adds cost. Factor this into your budget.
6. 6Identify your SIEM and SOAR integration requirements. Your EPP must feed telemetry to your existing security operations tools via documented APIs.
7. 7Request each vendor's most recent MITRE Engenuity ATT&CK evaluation results. Compare detection rates for the techniques most relevant to your threat model.
8. 8Plan a 30-day proof of concept on at least 200 production endpoints (not lab machines). Run two weeks in detect-only mode, tune exclusions, then enable prevention for the remaining two weeks.
9. 9Test the agent on your oldest and most resource-constrained hardware. Measure CPU, memory, and disk I/O impact under real-world conditions, not lab conditions.
10. 10Evaluate each vendor's update deployment process. After the CrowdStrike July 2024 outage, staged updates with customer-controlled timing are essential. Ask how updates are tested, staged, and rolled out.
11. 11Confirm the uninstall process for your existing endpoint security product. Legacy AV removal is often the most time-consuming part of migration. Request vendor-provided removal tools.
12. 12Negotiate contract terms: push for annual billing with the flexibility to increase endpoint counts without renegotiating the entire contract. Avoid multi-year locks unless the discount exceeds 25%.
