Top 10 Best Endpoint Detection & Response (EDR) Solutions in 2026

Endpoint detection and response (EDR) continuously records process, file, registry, and network activity on endpoints, applying behavioral analytics to identify attacker techniques while providing tools for investigation and containment. Several EDR platforms have emerged, each catering to different organizational needs: 1. CrowdStrike: Best overall for its rich telemetry and elite threat intelligence. 2. SentinelOne: Best for autonomous response, featuring strong containment and rollback capabilities. 3. Microsoft Defender for Endpoint: Best value for organizations already using Microsoft 365 E5. 4. Palo Alto Cortex XDR: Best for native data fusion across endpoint, network, and cloud telemetry. 5. Sophos: Best for generalist IT teams due to its user-friendly interface. 6. Trend Micro: Best for server and workload coverage, focusing on cloud and hybrid environments. 7. Bitdefender: Best mid-market value with strong detection capabilities at an accessible price. 8. Trellix: Best for organizations already using Trellix products, offering integrated solutions. 9. Huntress Managed EDR: Best for managed endpoint security, ideal for teams lacking full staffing. 10. Cisco Secure Endpoint: Best for Cisco environments, integrating well with Cisco security solutions. Key differentiators among these platforms include the analyst burden, alert management efficiency, and the impact of retention policies on investigation quality. The evaluation of EDR solutions should consider detection depth, response capabilities, operational costs, and the specific needs of the organization.

NordVPN’s Next-Gen Antivirus scores 94% in independent phishing and malware testing

NordVPN's next-generation antivirus achieved a 94% phishing detection rate in an anti-phishing test by AV-Comparatives, ranking third among nine products, behind Avast One Free Antivirus and Norton Antivirus Plus, both at 96%. The evaluation tested 250 live phishing URLs and recorded zero false positives for NordVPN, unlike competitors such as Malwarebytes Premium and Webroot SecureAnywhere. The two-percentage-point difference between NordVPN and the leaders corresponds to five URLs. Other products like Dr. Web Security Space and K7 Total Security had lower detection rates of 57% and 70%, respectively. Previously, NordVPN's Threat Protection Pro had an 83.42% detection rate across 3,209 links, outperforming IPVanish. In June 2024, NordVPN became the first VPN provider to earn AV-Comparatives' anti-phishing protection badge, requiring a minimum detection rate of 85% with zero false alarms. The antivirus feature is available on Plus plans and higher, previously known as Threat Protection Pro, and is included in Plus, Complete, and Prime tiers.

Scammers Impersonate Microsoft to Push Fake Security Scans and Refund Fraud

A network of fraudulent websites, branded as SysScan, has been discovered, which falsely claims to evaluate antivirus software effectiveness through deceptive security scans. These sites manipulate users into uninstalling legitimate antivirus products and disclosing sensitive personal and banking information. Eleven distinct domains associated with SysScan have been identified, all hosted on a single server. The fraudulent scans generate misleading results based on static findings rather than actual system assessments, and users are coerced into believing their computers are at risk. The scams misrepresent normal browser behaviors as security threats and instruct victims to uninstall their antivirus software, compromising their defenses. The operation targets both individual and business users, collecting extensive personal information and utilizing remote-access tools. The data submitted is sent to Telegram via its bot API. Users are advised to disconnect from the internet and secure their devices if they suspect they have been compromised. Indicators of compromise include specific IP addresses and domains associated with the scam.

You don’t want this Sleepwalker backdoor on your Windows machine

Malware researcher Dominik Reichel has discovered a sophisticated Windows backdoor named Sleepwalker, which remains dormant in memory until activated by a specially crafted network packet. Sleepwalker uses a 23-instruction command language to execute tasks, including running code in memory and exfiltrating data. It activates through a proprietary activation packet that does not contain readable commands. The malware targets a VMware VMCI and disguises itself as Microsoft's dpapi.dll, mimicking its functions while redirecting calls to a non-existent file. Once it confirms its host process as ERAAgent.exe, it enters a dormant state to evade detection. Sleepwalker monitors for a specific pattern known as a magic packet to decrypt and interpret commands. Commands sent to it are encrypted with AES-256-CCM and must be read in a specific order. The backdoor includes functionalities for sending and concealing data, receiving tasks, and executing programs. Reichel has developed a toolkit to decode Sleepwalker’s bytecode and a mitigation guide for affected users. However, there are significant gaps in knowledge regarding the initial access method, victim identification, and the malware's operator.
