Cyberattacks begin on a user workstation
A phishing email, an opened attachment, a compromised password… In the majority of incidents, the attack starts on a workstation, spreads silently, then strikes servers and critical data.
By the time the attack is visible, it is often already too late.
Traditional antivirus solutions detect known threats and react after the fact. Against advanced ransomware, lateral movements and fileless attacks, they quickly reach their limits.

Continuous monitoring of your endpoints
TYSCO EDR: see, understand and block the attack at the source
An EDR continuously monitors your company's workstations and servers. It immediately detects suspicious behaviour, even previously unknown threats. The moment a threat appears, the endpoint is automatically isolated.
- Continuous monitoring of workstations and servers
- Detection of abnormal behaviour
- Identification of an attack from its earliest signs
- Blocking before the attack spreads
- Immediate isolation of a compromised endpoint
- Limiting lateral movement
Not a tool delivered and forgotten
At TYSCO, our teams handle deployment, configuration, alert monitoring and response in the event of a real threat. Your business does not need to interpret complex alerts.
Deployment & Configuration
Tailored setup adapted to your infrastructure.
Alert monitoring
Our teams analyse and qualify every alert 24/7.
Behavioural analysis
Detection of suspicious behaviour before the crisis.
Immediate response
Rapid response in the event of a confirmed threat on your endpoints.
A key defence against ransomware
Against ransomware, the EDR can identify encryption behaviour, immediately isolate affected endpoints and prevent propagation to servers.
Blocking ransomware before it encrypts is the best defence.
EDR adapted to all structures
Antivirus, EDR or XDR — what's the difference?
EDR goes far beyond traditional antivirus. Here's why it has become the standard for organisations that take cybersecurity seriously.
TYSCO operates an enterprise-grade EDR solution, tailored for SMEs and local authorities.
EDR in action — what happened, minute by minute
Here is how TYSCO EDR responded to a real infection attempt on an employee's workstation.
Download from an infected website
An employee downloads a series of photos from a compromised website. The image files contain a concealed dropper, undetectable by a conventional antivirus solution.
The EDR detects abnormal activity the moment the image file is opened: an attempt to spawn an illegitimate child process, suspicious writes to a system directory and modification of registry keys. No antivirus would have identified this signature — it is behavioural analysis that triggers the alert.
Without waiting for human intervention, the EDR automatically disconnects the workstation from the corporate network. The user retains limited internet access for their session, but all access to network shares, servers and internal data is blocked. Propagation is stopped dead in under 3 seconds.
A qualified alert is immediately forwarded to TYSCO SOC analysts with full context: processes involved, execution tree, hashes of suspicious files, incident timeline. The team can take remote control of the workstation for in-depth investigation.
The malicious files are quarantined, suspicious processes terminated, registry modifications rolled back. The workstation is cleaned and reconnected to the network after verification. No data was exfiltrated, no other machine was affected. The employee resumes work within minutes.
Outcome: infection attempt blocked in under 4 minutes, with no manual intervention, no business disruption and zero propagation across the internal network.
Intentional deletion of company data
A departing employee deliberately deletes all files from their workstation and empties the shared folders they have access to: client documents, contracts, internal databases. The intent was to cause damage before leaving.
The EDR identifies abnormal behaviour in real time: more than 2,400 files deleted in under 90 seconds from a single user account, including mass access across network shares. The pattern matches no known legitimate operation — an alert is immediately raised.
The EDR immediately suspends the processes responsible for the deletions and cuts the account's access to network resources. The workstation is isolated. Ongoing deletion operations are interrupted — some files are thus preserved before any human intervention.
An insider threat alert is qualified and simultaneously forwarded to TYSCO analysts and management. The report includes: account identity, exhaustive list of deleted files, precise timestamps, affected network paths and an activity snapshot. All evidence is preserved for potential legal proceedings.
Thanks to incremental backups and snapshots active on the infrastructure, every deleted file is restored from the last backup point. No client data, no contract, no internal file is permanently lost. Normal operations resume 35 minutes after the incident began.
Outcome: 100% of deleted data recovered. Insider threat contained in 2 seconds, operations restored in 35 minutes, evidence preserved for legal proceedings.
Names and identifying details have been anonymised. These scenarios are representative of real incidents handled by TYSCO teams.
