Xcitium (formerly known as Comodo Security Solutions for enterprise) is a next-generation endpoint security platform that implements a Zero Trust approach to protect PCs, laptops, and servers from advanced threats. The hallmark of Xcitium’s solution is its patented Zero Dwell Containment technology, which guarantees that unknown or untrusted code can never harm your endpoints. In practical terms, Xcitium doesn’t rely solely on detecting malware (which can miss new threats); instead, it assumes every unrecognized file is malicious until proven otherwise and contains it in a secure environment. This prevention-first philosophy dramatically reduces the risk of zero-day attacks, ransomware, and other emerging threats that evade traditional defenses.

Here’s how Xcitium’s Zero Trust Endpoint approach works and what it offers:

• Auto-Containment of Unknowns: When an executable or script attempts to run on a device protected by Xcitium, the system instantly checks its reputation and safety. If the file is known good (trusted publisher or verified by Xcitium’s cloud intelligence) it executes normally. If it’s known bad, it’s blocked. If it’s unknown – which is often the case with brand-new malware or targeted attacks – Xcitium automatically runs it within a secure, isolated container (a virtual sandbox) on the endpoint. Inside this container, the file can do whatever it wants, but it has zero ability to make permanent changes to the system or access sensitive data. From the user’s perspective, there’s no disruption – they might not even realize a program was contained. Meanwhile, Xcitium’s engine analyzes the behavior of the file in containment: if it tries to encrypt files, modify the registry, or contact a command-and-control server, those actions are all happening in a bubble. If the file is later deemed safe, it can be released; if not, it’s eliminated. This strategy ensures “zero dwell time” for unknown threats – they are neutralized in real-time, before they can do damage.
• Advanced Endpoint Protection (AEP): Apart from containment, Xcitium includes all the features of a modern Endpoint Protection Platform (EPP). It has an AI-driven antivirus that catches known malware using signatures and machine learning models. It also employs behavioral detection to identify ransomware or file-less attacks in memory. For example, if a trusted application starts behaving strangely (perhaps it’s been hijacked), Xcitium can detect that anomaly and stop it. This layered approach means that Xcitium doesn’t rely on one method alone; it combines traditional detection with Zero Trust containment, covering each other’s gaps.
• Endpoint Detection & Response (EDR): Xcitium provides EDR capabilities, which allow security teams to investigate and respond to incidents on endpoints. It logs detailed endpoint activity (process launches, file changes, network connections) and can visualize the sequence of events in an attack (for instance, showing that a user opened an email, which launched Word, which spawned a PowerShell script, etc.). If something did get contained, the EDR view will show its behavior and any attempted actions. Analysts can then make an informed decision about the file (e.g., add to global blacklist). EDR also supports threat hunting – querying endpoints for indicators of compromise. This turns Xcitium into not just a protective tool but also a powerful visibility and response platform for incident responders.
• Cloud-Based Verdicting (Threat Intelligence): Xcitium leverages cloud intelligence to quickly classify unknown files. When a file is contained, it’s uploaded (in a safe manner) to Xcitium’s cloud for analysis by an array of engines – static analysis, machine learning, and human expert review if needed. The platform maintains a massive whitelist/blacklist database. Often, within minutes or faster, the cloud will return a verdict: malicious or benign. If malicious, all endpoints globally can now block that file; if benign, it can be allowed to run normally next time. This cloud-connected system means Xcitium endpoints are continually learning from each other’s experiences, bolstering the collective defense.
• Zero Trust Default Deny Posture: In summary, Xcitium enforces a “Default Deny” posture on the endpoint – only known good is allowed to run freely. But it smartly avoids the user disruption typically associated with default deny (which in the past meant lots of prompts or things breaking) by using containment. Users can still execute their applications and work as usual, while the security risk is mitigated behind the scenes. This model aligns perfectly with Zero Trust principles: don’t trust any code or process by default. As Xcitium’s CEO put it, detection-based models inevitably miss some unknown malware, which is why breaches happen; Xcitium instead "contains all unknown objects... preventing attacker damage". Contained attacks are effectively rendered harmless, and even if an attacker slips in, they find themselves in a cage.
• Additional Features: Xcitium’s endpoint suite also offers device control (managing use of USB drives, etc.), firewall, and host intrusion prevention systems (HIPS) to block exploit techniques. It supports centralized management so IT admins can deploy policies, updates, and view alerts from a single console. It covers Windows, and often Mac and Linux devices as well, to ensure all endpoints in the organization are protected under the same framework.

In practice, organizations using Xcitium have a very strong defense against ransomware and unknown threats. Even if an employee unknowingly runs a new ransomware strain, Xcitium will immediately contain that executable. The ransomware might think it’s encrypting the disk, but in reality it’s locked in a virtual safe – the real system is untouched. This approach has saved many companies from what would have been devastating incidents. It’s also a safety net for zero-day attacks (which traditional antiviruses have no signature for) – those zero-days will hit a wall of containment.

ICM Connect provides Xcitium to customers who require this high level of endpoint protection. We assist with deployment (which can be as simple as installing an agent on endpoints and configuring policies), and we can integrate Xcitium with your broader security operations. For example, alerts from Xcitium can feed into your SIEM, and containment events can trigger notifications to your SOC. We also help in fine-tuning the balance between security and operations – ensuring any specialized in-house applications are recognized by the system to avoid unnecessary containment (whitelisting safe internal apps, for instance).

With Xcitium’s ZeroDwell containment and ICM Connect’s support, you gain confidence that even the most sophisticated or unforeseen threats will be caught and neutralized on your endpoints. This greatly reduces the likelihood of breach and data loss, complementing your network and cloud security layers. In short, Xcitium turns the endpoint from a potential easy target into a hardened last line of defense that aggressively challenges anything untrusted – exactly what a Zero Trust architecture demands.
