Extended Detection and Response (XDR) is touted as a consolidation of technologies and disparate system monitoring into a single tool or suite of tools that provides extended visibility, analysis, and response across networks and cloud environments. XDR claims to be a more sophisticated and advanced progression of Endpoint Detection and Response (EDR) security. EDR tools contain and remove threats on endpoints and workloads, while XDR extends those capabilities beyond endpoints to multiple security control points. This includes email, networks, servers, and cloud environments to detect threats faster using data collected across various domains. Greater visibility and correlation are a good thing if it works.
XDR represents a major step forward in enterprise security capabilities. Since XDR has access to raw data collected across the environment, in theory, it can detect bad actors that are using legitimate software to gain access to the system. It performs automated analysis and correlation of activity data, allowing security teams to potentially identify and contain threats more effectively. For example, it can extend to include network detections, lateral movement, anomalous connections, beacons, exfiltration, and delivery of malicious artifacts.
Finally, like EDR, XDR responds to the threat in order to contain and remove it, and with XDR’s greater visibility and data collection across the environment, analysts and SOCs can take more authoritative actions on impacted assets. However, CyberHoot would caution against blinding automating these responses, as there is a strong potential for unintended consequences. In all cases, repeated testing and trial and error are essential to a successful XDR setup and automated response capability.

CyberHoot’s Minimum Essential Cybersecurity Recommendations
The following recommendations will help you and your business stay secure with the various threats you may face on a day-to-day basis. All of the suggestions listed below can be gained by hiring CyberHoot’s vCISO Program development services.
- Govern employees with policies and procedures. You need a password policy, an acceptable use policy, an information handling policy, and a written information security program (WISP) at a minimum.
- Train employees on how to spot and avoid phishing attacks. Adopt a Learning Management system like CyberHoot to teach employees the skills they need to be more confident, productive, and secure.
- Test employees with Phishing attacks to practice. CyberHoot’s Phish testing allows businesses to test employees with believable phishing attacks and put those that fail into remedial phish training.
- Deploy critical cybersecurity technology including two-factor authentication on all critical accounts. Enable email SPAM filtering, validate backups, and deploy DNS protection, antivirus, and anti-malware on all your endpoints.
- In the modern Work-from-Home era, make sure you’re managing personal devices connecting to your network by validating their security (patching, antivirus, DNS protections) or prohibiting their use entirely.
- If you haven’t had a risk assessment by a 3rd party in the last 2 years, you should have one now. Establishing a risk management framework in your organization is critical to addressing your most egregious risks with your finite time and money.
- Buy Cyber-Insurance to protect you in a catastrophic failure situation. Cyber-Insurance is no different than Car, Fire, Flood, or Life insurance. It’s there when you need it most.
Each of these recommendations, except cyber-insurance, is built into CyberHoot’s product and virtual Chief Information Security Officer services.
