Behavioural detection
Detection based on what code does — not just what it looks like — catching novel and fileless attacks.
Layered Defence — Layer 2 of 7
The Devices Layer
Securing the laptops, servers, and endpoints where work happens.
Every laptop, server, and virtual machine is a place where an attack can land and grow. Devices travel outside the network, run the applications attackers exploit, and hold the local data and credentials that turn one compromise into many.
The Devices layer has two complementary jobs: detect and contain malicious activity on endpoints the moment it starts, and shrink the attack surface continuously by knowing every asset you have and fixing the weaknesses attackers would use to get in.
Endpoint Detection & Response
EDR is a security solution that monitors, detects, and responds to threats on endpoints in real-time using advanced analytics and automation.
Traditional antivirus compares files against signatures of known malware — and modern attacks routinely sidestep it with new variants, scripts, and techniques that abuse legitimate tools. EDR takes a different approach: it continuously records what is happening on the endpoint — processes, file changes, registry activity, network connections — and watches that behaviour for the patterns of an attack.
That behavioural lens is what catches ransomware mid-encryption, fileless attacks living in memory, and an attacker quietly moving from one machine to the next. When something is detected, response is immediate and surgical: isolate the device from the network while keeping it reachable for investigation, kill the malicious process, quarantine files, and in some cases roll back the changes made.
The recorded telemetry also answers the questions that matter after an alert: where did this start, what did it touch, and is it anywhere else? That history is what turns incident response from guesswork into a timeline.
What to look for
One-click isolation
Cut a compromised device off from the network instantly while investigators retain access to it.
Automated response
Kill processes, quarantine files, and where supported roll back malicious changes without manual intervention.
Recorded telemetry
A searchable history of endpoint activity for investigation, threat hunting, and root-cause analysis.
Coverage breadth
Support for the platforms you actually run — workstations and servers, Windows, macOS, and Linux.
Asset & Vulnerability Management
Asset and Vulnerability Management identifies, assesses, and prioritizes risks across IT assets to proactively remediate vulnerabilities and strengthen overall security posture.
You cannot protect what you do not know exists. Asset management is the foundation: continuous discovery of every device, server, and system in the environment — including the unmanaged and forgotten ones, which are precisely the machines attackers find first.
Vulnerability management then assesses those assets for known weaknesses: missing patches, insecure configurations, end-of-life software. The hard part is not finding vulnerabilities — any scanner produces thousands — it is prioritization. Mature programs rank findings by real risk: whether an exploit is actively being used, whether the asset is exposed, and how much damage a compromise would cause. A medium-severity flaw on an internet-facing system can matter far more than a critical one on an isolated machine.
The output is a remediation loop, not a report: findings routed to the teams who fix them, verified once fixed, and trended over time so the organization can see its exposure shrinking — evidence that effort is becoming posture.
What to look for
Continuous asset discovery
An always-current inventory of devices and systems, including the unmanaged ones nobody documented.
Authenticated scanning
Credentialed assessment that sees missing patches and misconfigurations an outside-only scan would miss.
Risk-based prioritization
Ranking by exploitability, exposure, and asset criticality — not just raw severity scores.
Remediation workflow
Findings assigned, tracked, and verified as fixed — closing the loop instead of producing shelf-ware reports.
Posture trending
Measurement over time, so leadership can see exposure decreasing rather than a snapshot of problems.
Part of a Layered Defence
No single technology can protect against every threat. The Devices layer works alongside six other security layers, each creating another barrier an attacker has to defeat — and another opportunity to detect them.
- 1. Human
- 2. Devices
- 3. Network
- 4. Identity
- 5. Data
- 6. Monitoring
- 7. Response
How FioSec Helps
