Traditional antivirus waits for a known virus. SentinelOne watches what every program actually does — and when something starts acting like an attack, it stops it, isolates the device and can roll back the damage. Automatically, in seconds, with or without an internet connection.
Traditional antivirus compares files against a list of known viruses. Modern attacks change every day, hide inside legitimate tools, or never write a file at all. If it's not on the list, antivirus doesn't see it.
| Traditional antivirus | SentinelOne (EDR / EPP) | |
|---|---|---|
| How it detects | Signatures — a list of known viruses | AI and real-time behavior analysis of every process |
| New (zero-day) threats | Missed until the list is updated | Caught by what they do, even if never seen before |
| Fileless attacks | Usually invisible | Detected through anti-exploitation and script analysis |
| When it's offline | Protection weakens without updates | The AI runs on the device — protection continues offline |
| When something is found | Alerts and waits for a person | Kills, quarantines and can isolate the device automatically |
| After ransomware | Wipe and reinstall the computer | Roll the device back to its pre-attack state (Windows) |
| Understanding the attack | A file name in a log | A full Storyline of how the attack started and what it touched |
A lightweight SentinelOne agent runs on every laptop, desktop and server. It makes decisions locally, in milliseconds, and reports everything to the console ECSG monitors.
The moment a file lands on the disk, Static AI judges it — before it ever runs.
On-Write Static AIRunning programs are watched constantly. Encrypting files, injecting code or hiding in memory triggers an alarm.
Behavioral AIThe malicious process is killed and quarantined. If needed, the device is cut off from the network so the attack can't spread.
Autonomous response · IsolationIf ransomware managed to change files, the device can be rolled back to how it was before the attack.
Rollback (Windows)Every event is linked into one timeline, so ECSG knows exactly how it started and confirms nothing was left behind.
StorylineResult: an attack that once meant days of downtime becomes a non-event.
SentinelOne runs several detection engines at the same time. Each one is built to catch a different kind of attack, so a threat that slips past one is caught by another.
A machine-learning model inspects every new file the instant it's written to disk.
Monitors running processes for attack behavior: mass file encryption, code injection, privilege abuse.
Checks files against SentinelOne's cloud reputation and threat intelligence in real time.
Detects attacks that live in memory, abuse scripts (PowerShell, macros) or exploit software flaws.
Detection counts from ECSG-managed devices over the last 90 days.
These are real alerts from the last 90 days, described in plain English. Device names, users and companies are removed.
A user downloaded what looked like a normal game launcher. SentinelOne identified it as ransomware and mitigated it automatically — before a single company file was encrypted.
A program tried to load a malicious library in place of a legitimate one — a technique attackers use to run code quietly inside trusted software. Flagged as critical, investigated and confirmed by ECSG.
A network scanner appeared on a workstation. Attackers use these tools to map a network before launching ransomware, so ECSG verifies every one: was it authorized, or is someone looking around?
Several malicious files were detected while the browser was still downloading them — they never finished landing on the device.
An installer added itself to the Windows startup sequence, a classic persistence trick. ECSG investigated, confirmed it was legitimate software, and marked it as a false positive so it won't interrupt users again.
The AI acts in seconds. ECSG reviews every alert — so real threats are confirmed and legitimate tools keep working.
A snapshot from the SentinelOne console ECSG manages. Every number is real.
alerts were malware designed to steal data, spy on users or open the door to bigger attacks.
— the attack that shuts businesses down for days — was detected and mitigated automatically.
were the most targeted devices: the ones that travel, connect to home and public Wi-Fi, and download the most.
The same console gives ECSG a clear picture of every device, so we fix weaknesses before attackers find them.
Applications with known security flaws are identified across your devices, so they can be updated or removed.
We see every device's protection status and fix any agent that is out of date or offline.
Reporting on endpoint protection posture helps answer the security questions insurers ask at renewal.
Endpoint protection is where we start. As your environment grows, the SentinelOne Singularity platform can extend the same AI protection to other parts of your business.
Prevention, detection, autonomous response and rollback on Windows, macOS and Linux.
Protects servers, containers and workloads running in Azure, AWS or Google Cloud.
Detects attempts to steal or misuse user credentials inside the corporate network.
Collects security logs in one place and lets analysts investigate threats with an AI assistant.
Yes. SentinelOne is a next-generation replacement for traditional antivirus, combining prevention (EPP) and detection and response (EDR) in one agent. We remove the old antivirus during deployment so the two don't conflict.
The agent is designed to be lightweight. Because it doesn't depend on large daily signature downloads or heavy scheduled scans, users typically don't notice it running.
The AI runs directly on the device, so protection continues without an internet connection. When the laptop reconnects, it reports everything back to the console.
On Windows devices, SentinelOne can roll back files and system changes made by the attack to their pre-attack state, using the operating system's snapshots. We still recommend a full backup strategy as an additional layer — see our Backup & Disaster Recovery service.
ECSG reviews every alert. If a legitimate business application is flagged, we confirm it's safe and add an exclusion so it keeps working — like the real false-positive example on this page.
We'll review how your devices are protected today, show you the gaps, and explain in plain language what SentinelOne would change. No obligation.
Secure. Reliable. Human.
