5 things SOC teams hate about legacy EDR platforms
From alert overload to opaque pricing, legacy EDR creates more work than it prevents. Here's what SOC teams complain about - and what to look for instead.
Talk to any SOC analyst who has lived through a legacy EDR deployment, and you’ll hear the same five complaints. The technology works - mostly - but the operational overhead can be brutal.
1. Alert volume with no triage intelligence
Mid-size environments running CrowdStrike Falcon or SentinelOne Singularity routinely produce hundreds of alerts per day. The problem isn’t the volume alone - it’s that every alert arrives with the same flat context: process name, parent, command line, detection rule. No explanation of what it means, no suggestion of what to investigate first, no clustering of related events across endpoints.
That means every alert requires a human analyst to open it, dig into the process tree, cross-reference the endpoint history, and make a call. Multiplied across hundreds of alerts, that’s a full-time job for an analyst who should be hunting, not triaging.
AI-powered triage - delivered asynchronously so it never blocks alert ingestion - changes this. Alert explanation, incident clustering, and suggested next steps can cut time-per-alert significantly. Most legacy platforms either don’t offer it or charge for it as a separate module.
2. Opaque pricing and annual lock-in
Ask CrowdStrike, SentinelOne, or Elastic Security what their EDR costs. You’ll get a sales call and a proposal three weeks later with annual commitments, minimum seat counts, and module fees that weren’t in the demo.
The actual market range for standalone EDR sits somewhere between £8 and £25 per endpoint per month depending on features and volume. Few vendors publish this. Instead, pricing opacity lets them discount selectively, lock you into multi-year contracts before you know the real cost, and charge separately for capabilities that should come standard.
| Practice | Legacy EDR | Transparent alternative |
|---|---|---|
| Pricing | Quote-on-request | Published per-endpoint rate |
| Contract | Annual minimum seats | Month-to-month available |
| Add-ons | AI triage, MSSP tools extra | Included or clearly listed |
3. Heavyweight agents that break things
Kernel-level agents that load kernel modules are powerful, but fragile. CrowdStrike’s 2024 global outage - triggered by a faulty content update in a kernel driver - was the most visible example of a structural risk that comes with any EDR running at ring 0. It wasn’t a fluke; it’s a consequence of the architecture.
The day-to-day version of the same problem is less dramatic but just as real: elevated CPU during scans, memory pressure on older hardware, incompatibility with other kernel-level security tools, and painful uninstall procedures when you need to switch vendors. A 200-agent deployment on a mixed hardware estate can see measurable endpoint slowdown.
A static binary with userspace telemetry doesn’t carry the same crash-risk profile. Smaller footprint, no kernel dependency, simpler lifecycle management.
4. Multi-tenancy as an afterthought
Platforms designed for single-organisation deployments and later adapted for MSSPs tend to show the seams. You typically get a top-level tenant with child tenants underneath, billing that doesn’t map cleanly to client accounts, and alert queues that require careful ongoing configuration to keep properly separated.
For an MSSP managing 20 or 30 client environments, clean separation of telemetry, per-client alert queues, and the ability to onboard or offboard environments without touching shared configuration isn’t a nice-to-have - it’s the product. Bolted-on multi-tenancy rarely delivers it without workarounds that become technical debt.
5. No honest MITRE ATT&CK coverage map
Legacy vendors publish marketing heatmaps with lots of green cells and few caveats. What those maps don’t show: which sub-techniques require a paid add-on to actually detect, which ones fire with high confidence versus in theory, and which are Windows-only.
A vendor willing to say “we detect T1055 process injection behaviourally in real time on Linux and Windows, but T1134 token impersonation is Windows-only and produces noisy detections” is more useful than one that shows you a fully green heatmap and changes the subject. Buyers deserve to know what they’re actually getting before they sign.
These aren’t niche complaints - they’re the reason SOC analysts burn out and MSSP operators watch their margins erode. If any of them sound familiar, get in touch and we’ll walk through how LightEDR approaches each one.
