Your antivirus misses what's already inside.
Old-school antivirus matches files against a list of known bad ones. Modern attackers don't use known-bad files — they use the trusted Windows tools your team already uses and turn them against you. We deploy software that watches what programs are actually doing, not just what they're called.
What you actually need vs. what you already have.
The most common buyer question is 'Windows Defender is free with Microsoft 365 — why isn't that enough?' Here's the honest answer.
| Windows Defender (free w/ M365) | Defender for Endpoint P2 | CrowdStrike / SentinelOne | Senator-managed EDR | |
|---|---|---|---|---|
| Behavioral detection | Basic | Yes | Best-in-class | Best-in-class + tuned |
| Automated rollback | No | Limited | Yes | Yes (verified) |
| Threat hunting hours included | None | None | Add-on | Included monthly |
| macOS + Linux coverage | Limited | Yes | Yes | Yes |
| Who reads the alerts | You | You | You (or add MDR) | Our analysts, 24/7 |
| Exclusions + tuning | DIY | DIY | DIY | We own it |
What's included.
- 01
Agent deployment plan
Phased rollout across Windows, macOS, Linux, and container workloads — no surprise reboots, no help-desk flood.
- 02
Exclusions & tuning
Day-one suppression of legitimate dev tooling, build agents, and engineering workflows so security stops being the team that breaks productivity.
- 03
Custom detection rules
Industry-tuned content packs — healthcare, legal, financial — layered on top of the vendor's baseline.
- 04
Monthly threat-hunting hours
Active hunts against your telemetry for behaviors that didn't trip any rule. We find things before they fire.
What behavior-based protection actually catches.
Old antivirus matches files against a list of known bad ones. None of these attacks come with files on that list.
Regular Windows tools used as weapons
Attackers use built-in Microsoft tools — PowerShell, certutil, mshta — to do their dirty work. Old antivirus sees Microsoft's signature and shrugs. Behavior-based protection sees the unusual things those tools are being asked to do.
Attacks that leave no files behind
The harmful code runs entirely in memory and never gets written to disk. File scanners have nothing to scan. Behavior watchers notice the strange activity in real time.
Ransomware locking up your files
When a single program suddenly starts modifying thousands of files at once, that's not normal. We spot it within seconds and roll back the damage before it spreads.
Vulnerable drivers used as a back door
A common 2026 trick: attackers install a legitimate-but-flawed driver and use its bugs to turn off your security software. We watch for driver installs and stop them.
Platforms we deploy and operate.
What we measure (and send you every month).
Every laptop and server should have the agent running. We chase the stragglers.
When ransomware starts encrypting, how fast we reverse the damage.
After the first month of tuning, almost every alert is a real one.
Share of incidents we catch before any actual damage is done.
Who needs this.
- Hybrid and remote-first firms — endpoints leave the building daily.
- Anyone with BYOD policies or contractor access on managed devices.
- Healthcare, legal, and financial firms with regulated data sitting on laptops.
- M&A acquirers absorbing endpoints from a target whose security posture is unknown.
- Any cyber-insurance applicant in 2026 — EDR is now a standard requirement on every renewal questionnaire.
Q01I already have Windows Defender. Isn't that enough?
I already have Windows Defender. Isn't that enough?
It's a fine foundation — but free Defender misses everything behavioral and you have no one watching the alerts. Defender for Endpoint P2 closes most of the technical gap; running it managed closes the operational one.
Q02What about macOS and Linux?
What about macOS and Linux?
Covered. CrowdStrike, SentinelOne, and Defender for Endpoint all ship robust agents for macOS and major Linux distributions. Coverage parity is a 2024-and-later reality.
Q03Will it slow down my machines?
Will it slow down my machines?
Modern EDR is unobtrusive — typically 1-3% CPU and minimal memory. The audible difference is during full scans, which we schedule outside working hours.
Q04EDR vs XDR — what's the actual difference?
EDR vs XDR — what's the actual difference?
EDR sees endpoints. XDR sees endpoints + identity + email + cloud + network in one timeline, so you can trace 'phished email → credential use → endpoint behavior → cloud action' without pivoting tools. XDR is the 2026 default for serious deployments.
Q05Can attackers disable your agent?
Can attackers disable your agent?
It's a real threat — BYOVD attacks specifically try this. We pair EDR with kernel-protected anti-tamper, alerting on driver loads, and SOC monitoring that notices when an agent stops checking in.
