Nucleon Smart Endpoint

Endpoint Detection & Response (EDR) has rapidly grown as organizations seek confirmation of whether Endpoint Protection Platforms (EPP) and other controls failed, whether endpoints were compromised, and whether data was exfiltrated. Targeted attacks and corporate espionage represent meaningful portions of breaches, with malware and account takeovers frequently involved. A core EDR objective is reducing Mean Time to Detect (MTTD) and Mean Time to Respond (MTTR), since attackers can remain undetected for months.

EPP, evolving from antivirus, is now mature and broadly deployed, focused on identifying malicious code and preventing execution while adding functions like endpoint firewalling, URL filtering, and application control. EDR complements EPP by collecting and analyzing Indicators of Compromise (IoCs) such as bad hashes, IPs/URLs, anomalous ports, process injections, module load modifications, and registry changes. Modern EDR platforms centralize logs, enable remote endpoint examination, provide investigative reports, and support threat hunting and forensics with capabilities like event correlation, interactive querying, memory analysis, and recording/playback. Automation via playbooks can drive actions from evidence collection to quarantine, process termination, and restoration, often forwarding events to SIEMs.

Nucleon Smart Endpoint (launched by Nucleon Security, founded 2015; product available 2018) delivers EPDR through Prevention, Detection, Response, and Remediation using a single agent. Its distinctive prevention strategy applies multi-layer Zero Trust at the process level plus ML-enhanced static analysis (no signature scanning, sandboxing, or advanced runtime behavioral/memory analysis), VirusTotal sample sharing, and CVE visibility. It builds per-endpoint allow/deny execution rules by “absorbing” normal workflows, extends rules to file access, network controls, and limited DLP, and supports hardening (e.g., PowerShell limits, port constraints, driver installation prevention). Detection emphasizes unsupervised anomaly models updated daily and “living off the land” behaviors (LOLBAS). Remediation includes quarantining, deletion, blocking, termination, and full rollback using Windows Volume Shadow Copy, typically with conservative automation. Key gaps include SOAR integration, stronger default MFA options, richer runtime detection, and improved asset discovery/UEM integration.

• Targeted attacks account for 11% of cybersecurity breaches.
• Acts of corporate espionage account for 13% of cybersecurity breaches.
• Malware is involved in 48% of attacks.
• Account takeovers are involved in 14% of attacks.
• EDR collects and analyzes Indicators of Compromise such as MD5 hashes, known bad IPs/URLs, process injections, and registry changes.
• EDR playbooks can trigger actions including evidence collection, process termination, quarantine, and full endpoint restoration.
• EDR systems typically output event information to SIEM platforms.
• Nucleon Security was launched in 2015 in France.
• Nucleon Smart Endpoint was first made available in 2018.
• Nucleon Smart Endpoint uses Windows Volume Shadow Copy to support system rollbacks.

• “EDR is not a substitute for EPP, but rather a complement to EPP, email/web gateways, Network Detection & Response (NDR), and Distributed Deception Platforms (DDPs) as important components of modern security architectures.”
• “A main goal of EDR is often reducing the Mean Time to Detect (MTTD) and Mean Time To Respond (MTTR) to security incidents…”
• “Security professionals refer to such data points as Indicators of Compromise (IoCs).”
• “Zero Trust Architecture implies authentication and authorization for every action in a given system.”
• “By default, unapproved binaries are not allowed to execute.”
• “Nucleon Smart Endpoint ‘absorbs’ normal user activities and workflows to develop a baseline of normal user-to-process interaction.”
• “The models are updated daily, and clients can benefit from updates to detection models without having to modify the rules or deploy updates manually.”
• “Nucleon Smart Endpoint concentrates on finding malicious activities used by malware in ‘living off the land’…”
• “Responses begin with automation of investigation tasks.”
• “Most customers choose to allow less severe actions to be automated… rather than more intrusive actions such as node isolation and full system rollbacks.”
