XenSecure | Threat Detection & Response
Threat Detection & Response for Los Angeles Businesses
Antivirus is an important first layer of protection. But not every attack looks like a virus, and no preventive technology catches everything.
Xentric's Threat Detection & Response service continuously watches your computers and servers for suspicious activity, backed by a 24/7 security team that investigates real threats and responds when something needs attention.
Think of it as managed threat protection: technology watching what your devices are doing, security analysts watching the technology, and Xentric making sure the response fits the rest of your environment.
Every Threat Detection & Response plan starts with continuous monitoring of your computers and servers, backed by a 24/7 security team.
For businesses that need broader visibility, monitoring can also extend into systems such as firewalls and identity platforms. That additional layer is useful when the environment is more complex, or when audit and compliance requirements call for centralized security logging.
The endpoint technology behind the core service is commonly called EDR. The broader logging layer uses a SIEM.
the problem
Not every attack looks like a virus
An attacker may log in with a stolen credential and then use PowerShell, remote-access software, or administrative tools that already exist on the computer. The tools themselves may be perfectly legitimate. What matters is how they are being used.
That's why modern endpoint security has to look at more than whether a file is known to be malicious. It also needs to recognize when otherwise normal activity starts behaving like an attack.
A quick gut check:
- If someone started using legitimate tools on one of your computers in a malicious way, would anyone recognize what was happening
- Is anyone actually watching your endpoints at 2am, or does an alert just sit there until someone opens their inbox
- If a device were behaving strangely right now, would you find out today, or whenever someone happens to notice
If any of those feel uncertain, that uncertainty is the gap this service closes.
why it works
Watching behavior, not just known malware
The endpoint detection layer looks beyond whether something is already known to be malicious. It also watches what the device is doing: unusual processes, administrative tools behaving unexpectedly, attempts to establish persistence, or signs that someone may be moving from one system to another.
This kind of technology is commonly called Endpoint Detection and Response, or EDR.
the differentiator
Detection is only useful if someone responds
A security tool that only generates alerts still leaves the hardest part to you: determining whether something is real and deciding what to do about it.
Threat Detection & Response includes the people needed to make those decisions. Security analysts investigate suspicious activity around the clock, validate real threats, and take appropriate containment action instead of leaving everything in a dashboard for your team to sort through.
That's what we mean by managed threat protection. The technology isn't left to run unattended.
the difference
Prevention and response solve different problems
You still want endpoint protection. Threat Detection & Response adds the monitoring, investigation, and response layer around it, which is why this service works alongside your antivirus instead of replacing it.
Endpoint Protection
- Works to prevent malicious activity
- Automatically blocks many threats
- Focuses on protecting the endpoint
- May generate alerts that require review
- Stops what it can automatically
Threat Detection & Response
- Watches for suspicious behavior that may indicate an attack
- Adds investigation when activity needs context
- Looks for signs such as persistence, lateral movement, or misuse of legitimate tools
- Security analysts review meaningful activity 24/7
- Can contain an affected device and coordinate what happens next
what's included
What's included with Threat Detection & Response
Every plan starts with device-level threat detection, 24/7 investigation, and response. Broader security monitoring can be added when your environment or compliance requirements call for it.
Core Protection
Continuous Device Monitoring
Watches supported Windows, macOS, and Linux devices around the clock for suspicious behavior and attack patterns that may not be obvious from malware detection alone.
24/7 Security Analyst Monitoring
A live security team reviews suspicious activity around the clock and investigates signs of ransomware, persistence, lateral movement, and other attack behavior instead of leaving detection to automation alone.
Analyst-Validated Threats
Security analysts investigate suspicious activity before it reaches your team, so you're not handed a raw queue of alerts and expected to determine which ones matter.
Automatic Containment
When a serious threat is confirmed, the affected device can be isolated from the rest of your environment to help stop the attack from spreading while it's investigated.
Remediation and Incident Reporting
Once a threat is contained, you get clear documentation of what happened, what was done, and what still needs attention, instead of a technical alert your team has to decipher.
Works With Your Existing Protection
Adds monitoring, investigation, and response alongside compatible antivirus, including Microsoft Defender. You're adding another security layer, not replacing everything already protecting your computers.
Optional Broader Monitoring
Most businesses start with Threat Detection & Response focused on their computers and servers. Some environments need a wider view: broader monitoring can bring activity from systems such as firewalls and identity platforms into the same security operation, helping analysts see attacks that cross multiple parts of the environment. The technology used to centralize and analyze that information is commonly called a SIEM.
Security Activity in One Place
Brings relevant activity from systems such as firewalls and identity platforms together so suspicious events can be evaluated in context instead of sitting in separate dashboards.
See Attacks That Cross Systems
A security incident doesn't always stay on one computer. Broader monitoring helps connect activity across a device, user account, firewall, or other security system so investigators can see the larger pattern.
Centralized Logging and Reporting
Centralized security records can help document relevant controls and activity for audits, cyber insurance applications, and client security questionnaires without assembling the history by hand.
our approach
We don't automatically put every client on the biggest stack
Broader monitoring tends to make sense when a business has more complex infrastructure, multiple security systems that need to be correlated, specific logging requirements, or audits and client security reviews that require centralized records.
If your environment doesn't need that additional complexity, we don't see a reason to make you pay for it.
built for how you work
Added protection, not a system overhaul
Deployment is lightweight and works alongside the tools you already have, including Microsoft Defender, so there is no rip-and-replace and no disruption to how your team works day to day.
When immediate containment is needed, actions such as isolating a compromised device can happen quickly to keep the threat from spreading. More disruptive remediation steps are confirmed with your team before they're taken.
Your team sees a clear report of what happened and what was done, not a raw alert left for someone to decode.
why xentric
Security technology is only one part of the service
Security technology alone isn't something you turn on and forget. Coverage needs to stay current as devices are added and removed, incidents need to be connected back to the business, and recommendations need someone who understands your environment well enough to act on them.
The detection technology watches what is happening on your devices.
The 24/7 security team investigates suspicious activity and responds to confirmed threats.
Xentric makes sure the protection is deployed across the right systems, coordinates anything that needs attention in your environment, and connects what the security team sees to the rest of your IT and cybersecurity.
Together, that is managed threat protection.
part of xensecure
Threat Detection & Response is one layer of XenSecure
It works alongside email security, network security, and security awareness training.
A suspicious login may start with a stolen password. A malicious message may arrive through email. Activity may show up on a computer. An attacker may then try to move across the network. Those protections work better when they are treated as parts of the same security program instead of unrelated products.
