Endpoint and server protection: we test the response
EDR and hardening baselines deployed on SentinelOne, Microsoft Defender or your platform, then validated per endpoint: tamper protection, policies, isolation.
Why this matters
An EDR agent installed isn't an EDR agent working. Rolling out an EDR platform or hardening baseline is only step one: policies drift, agents go stale, and isolation actions that were never tested can fail exactly when you need them.
Silent agent drift
Endpoints get reimaged or replaced, and the EDR agent doesn't always come back with them.
Protection quietly disabled
Real-time protection can be turned off for troubleshooting and never turned back on.
Untested isolation
An isolation response that has never been exercised is a guess, not a control.
Hardening that regresses
A hardened baseline can be quietly weakened by a later patch, driver or admin change.
What sets this apart
We test the response, not just the install. We don't just deploy your EDR and hardening policies: we go back and validate that tamper protection, real-time protection and isolation response actually work per endpoint, and hand you a specific action for anything that doesn't.
- EDR tamper protection: confirmed enabled and unremovable by a local admin.
- Policy coverage: every endpoint checked against the intended policy, not just the install count.
- Isolation response: tested end to end so it works the first time it's needed for real.
- Hardening baseline: re-checked for drift introduced after initial deployment.
Sample validation findings
Illustrative examples; they do not describe a specific client.
- High: EDR tamper protection disabled on nine endpoints after a driver update. Action: re-enable tamper protection via policy and add it to the deployment checklist.
- High: automated isolation did not trigger during the test scenario on two servers. Action: correct the network isolation rule and re-run the test before relying on it.
- Medium: a dozen endpoints are running an outdated agent version with a known detection gap. Action: force an agent update push and confirm version compliance.
- Low: a hardening baseline setting was reverted on four servers by a local administrator. Action: re-apply the baseline and restrict local override rights going forward.
What you get
EDR deployed and configured
Agents deployed on the endpoints and servers in scope, with detection and response policies tuned to your fleet, on the platform you choose or already own.
Hardening applied in stages
Security baselines applied to servers and workstations, sequenced and tested in stages so operations are not disrupted.
Per-endpoint validation
Tamper protection, policy coverage, real-time protection and isolation response verified on every endpoint, not just on an install counter.
A report with one action per gap
Every endpoint or server that fails validation gets a specific action.
Our approach
- Assessment. Analysis of your endpoint and server landscape, the EDR platform in place and the coverage gaps, to scope the engagement.
- Design. EDR policies and a hardening baseline tailored to your infrastructure and risk appetite, with a deployment order that protects critical systems.
- Deployment. EDR agents deployed or tuned, security policies configured and hardening measures applied in stages.
- Validation and report. Return per endpoint on tamper protection, coverage, isolation response and hardening drift; hand-off of the report with a specific action for each gap.
Works with what you have
Built around the EDR platform you choose. SentinelOne, Microsoft Defender, or the EDR platform you already own: we deploy and tune it before recommending a replacement.
After the engagement
An implementation engagement is a defined project. Recurring EDR checks and drift detection belong to Managed Security Operations; continuous scanning and remediation of vulnerabilities on those same endpoints, to vulnerability and patch management. The accounts that administer these endpoints are covered by the identity and access service.
Harden your endpoints before someone else finds the gap.

Frequently asked questions
- Which EDR platforms do you deploy?
- We work with leading EDR platforms such as SentinelOne and Microsoft Defender, and can work with a platform you already own: we deploy and tune it before recommending a replacement. What matters is not the brand of the agent, but the proof that tamper protection, real-time protection and the isolation response work on every endpoint.
- Will hardening disrupt our operations?
- We sequence hardening changes and test in stages to minimize disruption; critical systems are never changed without a plan. After deployment, the hardening baseline is re-checked for drift introduced by a later patch, driver or admin change, and local override rights are restricted where needed.
- What exactly do you test after deployment?
- Four points, per endpoint: EDR tamper protection, confirmed enabled and unremovable by a local admin; policy coverage, every endpoint checked against the intended policy rather than the install count; the isolation response, tested end to end; and the hardening baseline, re-checked for drift. Every gap comes with a specific action.
- Can monitoring continue after the project ends?
- Yes. The implementation engagement is a defined project that ends with the validation and the hand-off of the report. Recurring EDR checks, agent version tracking, hardening drift detection and vulnerability management can then be handed off to our Managed Security Operations team, on a documented cadence.
