EDR deployment and management

What this service is

Endpoint detection and response (EDR) is security software that runs on each laptop, desktop and server, records what happens on it, and flags behavior that looks like an attack. When something suspicious happens, such as a process trying to dump passwords or encrypt files, EDR can alert an analyst and, if needed, isolate the device from the network while the rest of the organization keeps working.

The software is only part of the value. Promatics handles the whole lifecycle: selection, deployment, tuning and management, and, for managed-service clients, 24/7 monitoring and response.

How EDR fits with the rest of your security

EDR catches what gets past other defenses, so it works best as one layer among several:

• MFA and account hygiene make stolen passwords less useful.
• Email security stops many attacks before they reach a device.
• Patching closes the weaknesses attackers use to get in.
• Tested backups mean you can recover if the worst happens.
• Awareness training helps staff spot and report what the tools miss.

Many cyber insurers now ask specifically whether EDR is deployed on all endpoints and whether its alerts are monitored. We document coverage and monitoring, so you can answer those questions accurately.

Platforms we work with

We deploy and manage EDR platforms including Microsoft Defender for Endpoint and Defender for Business, CrowdStrike Falcon, SentinelOne and Fortinet's FortiEDR. The right choice depends on your devices, the licenses you already own, how alerts will be monitored and your budget. If you already pay for EDR through another subscription, we start there.

Monitoring and response

An EDR alert is only useful if someone looks at it. For managed-service clients, we provide round-the-clock monitoring of key infrastructure, computers and servers, including nights and holidays. Alerts are triaged against agreed playbooks: some are closed as harmless, some lead to a call to your named contact, and serious ones can lead to isolating a device straight away. Response targets are set in the service agreement.

You receive regular reports showing detections, device coverage, devices that have stopped reporting and any recommended changes.

Common rollout problems we plan for

• Devices nobody knew about. Laptops that rarely connect, old servers and shared machines are often missing from the inventory. We compare the EDR console with your device management tool and directory until the numbers agree.
• Two security products fighting. Leaving old antivirus running alongside EDR can slow devices or cause conflicts. We remove or switch it to a compatible mode in a controlled order.
• Business software flagged as suspicious. Line-of-business applications, scripts and backup agents sometimes behave like malware. We test them in the pilot and add narrow, documented exclusions rather than broad ones.
• Alert fatigue. An untuned console produces noise that trains people to ignore it. Tuning in the first weeks is what makes later alerts worth acting on.

Data residency and vendor contracts

EDR platforms send device telemetry to the vendor's cloud. Where data residency matters to you, we check the storage locations each vendor offers and record the choice made. We also review the vendor's terms with your privacy obligations in mind; financial institutions should consider the interagency guidance on third-party risk management and the FFIEC IT Examination Handbook, and organizations handling health data should confirm business associate agreement requirements. This is not legal advice.
