Endpoint Detection & Response (EDR) is also known as Endpoint Threat Detection and Response. It is an integrated cybersecurity technology with the combination of real-time continuous monitoring and endpoint data analytics with rule-based automated response to mitigate malicious cyber threats.

At present, organization’s endpoints are exposed to continuous threats as one cyber-attack happens every 39 seconds. Most of the times, these attacks occur during the off days or during the long vacations. As most of the cyber teams are on vacation, that’s why attackers time these attacks for gaining access during vacation time. In order to protect the endpoints at that time. EDR is needed. According to studies, 90% of effective cyberattacks and 70% of successful data breaches occurs at endpoint. Though antivirus, anti-malware, firewalls, and other traditional endpoint security solutions have grown over time, they can still only detect known endpoint threats. They’re significantly less successful. They’re also useless against an increasing number of ‘fileless’ intrusions, which operate entirely in computer memory and skip file or signature scanning altogether. Most importantly, typical endpoint security tools cannot identify or neutralize emerging threats that bypass them. This enables adversaries to remain invisible and roam the network for months, gathering data and detecting vulnerabilities before launching a ransomware assault, zero-day vulnerability, or other large-scale cyberattack. EDR continues where these typical endpoint security solutions stop off. Its threat detection analytics and automated response capabilities can identify and contain possible attacks that infiltrate the network perimeter, typically without the need for human interaction, before they do significant damage. EDR also provides tools for security teams to identify, investigate, and prevent suspected and emerging risks on their own. EDR systems can automatically

  • Alert security analysts about specific threats or suspicious activities.
  • Prioritize alerts based on severity.
  • Create a ‘track back’ report that tracks an incident or threat’s path through the network to its root cause.
  • Disconnect or log users off the network.
  • Halt system or endpoint processes.
  • Prevent endpoints from executing malicious or suspicious files or email attachments.
  • Scan all endpoints on the network for the threat.

  • Gathering data: It firstly collects information about security threats from endpoints like laptops, mobile phones, and IoT devices.
  • Analyzing data: It then analyzes the information to find security breaches.
  • Automating response: Then EDR responds to threats based on discovered attack profiles.

  • Ingesting telemetry from endpoints: The solution collects telemetry data from endpoints by installing software agents on each endpoint through other, indirect means.
  • Sending the ingested telemetry to the EDR platform: The solution sends data from all endpoint agents to a central location, usually a cloud-based EDR platform as it works on a centralized mode. It can also work on-premises or as a hybrid cloud to help meet the requirements.
  • Correlating and analyzing data: In this solution, machine learning is used for correlating and analyzing the data. This solution uses this technology for establishing an overview of normal endpoint operations and user behavior and then looks for anomalies.
  • Identifying suspicious activity: The solution identifies suspicious activity and pushes alerts to notify security analysts and relevant persons. It also starts providing automated responses according to predetermined triggers
  • Responding to threats: The solution initializes automated responses according to predetermination. For example, it temporarily isolates an affected endpoint to block malware from spreading across the network.
  • Retaining data for future use: EDR solutions retain data to enable future investigations and proactive threat hunting. Analysts can make use of this data to consolidate events into one incident to investigate existing prolonged attacks or previously undetected attacks.

There are many features of EDR. Some of them are:

  • Automated Response: EDR solutions can automatically respond to threats on endpoints. This is especially true for threats that spread rapidly and do major damage before human intervention is available. Automated response capabilities may include quarantining infected data, preventing malicious network connections, or fully isolating an afflicted endpoint from the network. This enables security personnel to concentrate on investigating and addressing the problem without worrying about containment.
  • Analysis and Forensic: EDR tools enable security teams to do quick investigation and forensics on discovered threats. They provide useful information on the nature of the threat, such as its origin, operation, and mitigation. EDR technologies can observe endpoint behavior over time and can keep a track of it. It can produce a historical log of events that can be extremely useful during a forensic inquiry. This can assist security teams in determining the core cause of a security issue, understanding the full scope of the breach across numerous endpoints, and developing effective prevention methods for future occurrences.
  • Threats Intelligence: EDR solutions integrate with threat intelligence feeds, providing precise information on new threats and malicious actors. By combining this information, EDR tools can better detect and respond to emerging and sophisticated threats.EDR tools can match observed endpoint behavior to known threat indicators, which improves their capacity to detect malicious activity. This also enables them to issue alerts regarding potential risks.
  • Threat Hunting: Some EDR solutions provide advanced threat hunting capabilities. This proactive protection strategy includes seeking out symptoms of compromise or suspicious behavior within an organization’s network that automated systems may have missed. Threat hunting can detect stealthy and persistent attacks, such as Advanced Persistent Threats (APTs) and insider threats, which can get around typical security procedures. Furthermore, security providers might offer managed threat hunting services performed by their skilled security specialists.

Some benefits of EDR are highlighted below:

  • Threat Detection: Identifies and alerts to suspicious activities or behaviors in real time.
  • Incident reaction: Enables faster reaction to security incidents, reducing damage and delay.
  • Visibility: Provides extensive visibility into endpoints, allowing for better monitoring and management.
  • Forensics: Helps with post-incident investigation by providing extensive data on endpoint activity.
  • Compliance: Monitors and records endpoint activity to assist enterprises in meeting regulatory standards.
  • Endpoint Protection: Actively protects against malware, ransomware, and other threat. It reduces the risk of data breaches and cyber assaults by constantly monitoring endpoints.
  • Operational Efficiency: Automating threat detection and response processes improves security operations.
  • Asset Management: Helps to track and manage endpoints within the enterprise.
  • Scalability: Scales to accommodate the seamless increase of endpoints inside the organization.
  • Time Saving: Helps in saving time and resources with automation features and using a single EDR package.

There are many companies who provide EDR solutions such as Kaspersky, Sophos, Microsoft Defender, McAfee, CrowdStrike, Sentinel One, Cisco, Cynet, Carbon Black (presently known as VMware Carbon Black), TrendMicro and so many. These vendors are recognized for their comprehensive EDR solutions, including threat detection, response capabilities, and advanced features such as machine learning and behavioral analytics.

Many organizations work with these providers and give services to industries that requires the EDR solutions. Goinnovior is also present among these organizations. We help you in maintaining a safe and secure workplace by providing these services alongside many other services of cyber security such as providing firewall safety, endpoint security and so on.
