Endpoint Protection as a Service

Classic antivirus compares a file's signature against a database of known malware. Yet a significant share of current attacks never write a file to disk: the malicious code runs directly in memory, through PowerShell or WMI, and is automatically recompiled for each victim, producing a different signature every time. This is why EDR looks at the behavior chain, not at the file: the chain "Word document → launched PowerShell → opened an encrypted outbound connection → tried to delete shadow copies" is a ransomware pattern as a whole, even though each link looks harmless on its own, and it is cut off immediately. This behavior mapping against the MITRE ATT&CK framework provides protection against zero-day threats without waiting for a signature.

Take an example case: EDR detects that hundreds of files on an accounting computer have been encrypted in a short time and automatically isolates the device from the network; at that second, the attack is stopped from spreading to the file server. Our SOC analyst takes over the incident within 15 minutes: the initial infection vector (for example, a phishing attachment) is identified from the process tree, the same indicators (IoCs) are scanned across the whole device fleet, and the affected files are restored from shadow copies through rollback. At close-out, a root cause report and actions to prevent a recurrence (for example, a macro policy or an email rule) are presented to you. This entire flow runs at the same speed while your own team is asleep, and that is the essence of MDR.
