--- title: "Endpoint Security & EDR for SMBs | EFROS" description: "EDR with behavioral detection, pre-authorized containment, and 24/7 SOC response. Replaces basic antivirus on every device that touches your data." canonical: https://efros.com/security/endpoint/ --- - [Home](https://efros.com/) - /[Security](https://efros.com/security/) - /Endpoint Security Service · Endpoint Security & EDR # Detection plus authorized containment. Modern EDR replaces antivirus on every device that touches your data. We tune the detection content to your environment so it isn't generic noise. When something fires, our team isolates the host inside the window an attacker uses to move laterally. Under authority you grant us in the IR policy at onboarding, not a midnight phone tree. By [Stefan Efros](https://www.linkedin.com/in/stefanefros-cyberdefense/), CEO & Founder, EFROS Updated · June 4, 2026 ## Why endpoints are the front line. 01 ### Antivirus does not stop modern attacks Signature-based AV catches known malware. Modern attackers use living-off-the-land binaries, encoded PowerShell, and legitimate admin tools, none of which AV flags. 02 ### Endpoints are the front line Most ransomware events start with an endpoint that ran a malicious payload. Once attackers are on a device, lateral movement to file shares and identity is fast and quiet. 03 ### Detection without response is theatre An EDR that lights up alerts at 03:00 but cannot isolate the host until an analyst is paged is too slow. Containment has to execute in minutes. Pre-authorized, not improvised. 04 ### BYOD widens the surface Personal laptops and unmanaged phones touching corporate Microsoft 365 with no compliance enforcement. They show up in Conditional Access logs every day. They almost always pass. 05 ### Server endpoints are forgotten Workstation EDR is common. Server EDR is often missed. Most ransomware leaves the encryption job for a server because servers store the data and are usually under-monitored. ## What's included. - EDR deployment on Windows, macOS, Linux endpoints - EDR deployment on Windows / Linux servers + virtual machines - Behavioral detection content tuned to your environment - Pre-authorized containment actions (host isolation, account disable) - 24/7 SOC triage and response (Fortress SOC tier) - Attack Surface Reduction (ASR) rules + application control baseline - Patch management with critical-CVE escalation - Configuration drift monitoring against CIS benchmark - Mobile device management for iOS / Android (Intune) - Compliance enforcement: BitLocker, FileVault, screen lock, OS version - BYOD policies with conditional-access integration - Quarterly endpoint posture review ## Frequently asked. ### Which EDR platforms do you support? + Microsoft Defender for Endpoint, CrowdStrike Falcon, SentinelOne Singularity, Palo Alto Cortex XDR. We deploy what fits your stack and your budget. The operations layer (detection content, triage, response) is consistent across platforms. ### What does pre-authorized containment mean? + When EFROS engineers detect a high-confidence compromise, we can isolate the host, disable the account, revoke active tokens, and quarantine the file without paging your team for sign-off. The IR policy you sign during onboarding defines exactly what we can do unilaterally and what requires explicit approval. ### Will the EDR slow down user devices? + Modern EDR runs in kernel-mode with minimal overhead. Microsoft Defender for Endpoint and CrowdStrike Falcon both ship with default profiles tuned for performance. We measure user-impact metrics during pilot and adjust ASR rules if any cause friction. ### How fast does isolation happen after detection? + Pre-authorized containment executes in minutes once a high-confidence detection fires. Specific timing is contractually defined in the SLA appendix. Manual / authorized-only actions follow your normal IR escalation path. ### Do you replace antivirus or run in parallel? + Replace. Modern EDR includes the AV layer plus the behavioral detection AV cannot do. Running both produces conflicts and false positives without measurable security gain.
