Cyberattacks have become a new normal. Cybersecurity concepts like endpoint detection and response (EDR) have therefore become essential in ensuring the security of endpoints like laptops, desktops, and mobile devices. But if the number of devices increases across your organization, endpoint security may not be enough. You need to secure not just the endpoints but also your end-to-end network and other vulnerable communication methods like email.
So, what more you can add to your cybersecurity arsenal? You need to evolve your EDR cybersecurity solution into XDR (extended detection and response), which brings an integrated and automated approach to threat detection, investigation, and response for the whole environment.
In this post, we’ll take a look at what XDR means, why should you replace EDR with XDR, and the benefits of XDR.
What Is XDR?
XDR is an emerging technology that provides robust threat detection, response, and investigation capabilities for all endpoints. It coordinates an organization’s security efforts across its entire cloud estate.
XDR consolidates various security tools and layers, including endpoints, email, applications, and networks.
It can take in huge volumes of raw data from across multiple sources, connect insights, and provide deeper endpoint visibility after careful analysis. It frees up time for security analysts by handling repetitive tasks and removes malicious processes. It can automatically send alerts and create suspicious behavior profiles for various potential threats.
An XDR solution will use AI and Machine Learning to become more adaptive, improve awareness, and deal with the latest threats. It serves as a sequel to traditional EDR and extends the capabilities of EDR and MDR services combined.
Why is XDR better than EDR?
XDR solutions are easily scalable compared to traditional EDR security tools.
Where EDR tools provide only endpoint detection and protection, XDR gives you an upgrade by going beyond endpoints into network, application, and cloud security. Unlike EDR, XDR gives you detailed data and visibility about each endpoint such as network connections, file changes, and process activities. XDR can flag security alerts for analyst reviews and auto-heal affected assets quickly.
EDR delivers a unified view of security threats; it is limited to endpoint threat detection and response management.
Why Do We Need XDR?
We need XDR to achieve cross-layer visibility throughout the infrastructure.
XDR allows us to better understand threats and adds business context.
As your infrastructure evolves, so does the need to protect it from various cyber-attacks. A minor flaw can take your whole organization down.
It’s vital to deploy XDR to reduce or eliminate the following security risks:
- Unauthorized access to restricted zones
- Noncompliance with upcoming cyber security regulations
- Lack of regular patching or updates
- Malicious insider attacks and social engineering
- DDoS, brute force invasions, identity theft, and more
Benefits of XDR
The technology helps you eliminate various security risks. Here are the top XDR benefits:
#1. Comprehensive Threat Detection
The first benefit you get from XDR is enhanced threat detection and prevention. Since XDR covers more than just an endpoint, it provides you with a centralized monitoring platform. The platform aggregates data from multiple security tools and systems, such as endpoint security, network traffic, mail, software, and cloud environments.
Using the consolidated data, XDR allows you to easily and effectively identify and respond to all types of threats. By combining AI and ML, you can proactively mitigate any suspicious activity or potential threat before it causes harm to systems.
#2. Analysis of Internal and External Traffic
Centralized monitoring provides holistic views that go beyond just a single endpoint; XDR analyzes network traffic flows, including cloud-based environments.
XDR covers all attack surfaces present within the organization. It includes both external and internal traffic monitoring that attackers may exploit to compromise systems.
#3. Improved Visibility and Insight
XDR solutions underly unified data aggregation, giving you better visibility and insight into any threats or weak points in your infrastructure. Once you know what the weak points are, you can fix them quickly or set alerts in case an invader tries to exploit them.
Furthermore, XDR enhances the capability of security officials involved in cyber forensics and reporting. They get a complete overview of threats that help in the investigation process of attacks that occurred on the system.
#4. Enhanced Incident Response
XDR’s automated incident response workflows will enable you to respond to threats faster. The remediation times are cut short. You get adequate threat detection coverage and it provides rapid incident response.
XDR tools automatically prioritize critical incidents and provide real-time alerts. Its automated workflows execute predefined actions that quickly isolate threats to reduce their impact until security teams take necessary action.
In case one of your systems gets compromised, XDR tools disrupt the attack chain and reduce its overall impact; it separates compromised assets through automatic attack disruption—for example, by automatically disabling compromised user accounts; it can also block incoming and outgoing communications for suspected devices.
#5. Cost Efficiency
Since XDR contains a package of security solutions for your entire infrastructure, it saves you the cost of buying any overlapping or extra security tools. Additionally, it lowers operational costs with its comprehensive threat detection and automated incident response.
Rapid restoration services save customers from data outages, losses, and additional expenses associated with requesting outside support services.
#6. Continuous Business Operations
One of the downsides of a cyberattack is business disruption. And if business is disrupted regularly, users lose trust in the system and may use the service less.
XDR ensures business continues running smoothly by quickly restoring the service in case of a cyberattack or global outage. So, along with financial gain, you get user trust and reputational gain by implementing XDR.
#7. Seamless Integration
XDR in itself is scalable and flexible enough to integrate with existing security tools. It’s also compatible with multi-platform environments. Combining XDR with different security solutions further expands the capability of threat detection to address cyber threats.
Integrating XDR can also increase your response capability by streamlining and automating security operations.
#8. Better Management of Threat Alerts
Having multiple cybersecurity solutions can pile up false-positive threat alerts, leading to alert fatigue and performance degradation. You might waste time investigating false alarms, miss important alerts, and even become desensitized to legitimate ones.
XDR uses AI to reduce reliance on human resources. It reduces the number of false positive alerts and generates an alarm only when it finds real danger.
#9. Account Compromise and Insider Threats
Social engineering is one attack method where hackers don’t directly attack the network. Instead, they target people, like company employees, to extract sensitive information from them. They use collected intel to compromise the organization’s security. Sometimes, employees make deliberate attempts to leak information.
XDR analyzes the user activities of those who are logged into systems. For suspicious activity patterns like odd login times or access from unusual locations, XDR issues account compromise alerts.
These tools also alert security teams whenever insider attempts are made by tracking data movements and looking for signs of exfiltration.
