XenSecure | Email Security
Email Security for Los Angeles Businesses
Your inbox is still one of the easiest places for an attacker to reach your employees. Basic spam filtering does a good job with obvious junk and known threats, but it can still miss a message carefully crafted to look like it came from your CFO, your bank, or a vendor your team already trusts.
Xentric's managed email security service for Microsoft 365 adds the layers basic filtering leaves out, catching what gets past the gate and cleaning up quickly when something still gets through.
Xentric's email security service combines gateway filtering, behavioral threat detection, automated incident response, and Microsoft 365 backup into one managed service, instead of a single filter sitting at the front door.
The goal is coverage at every stage: prevent what can be stopped at the gate, detect what makes it through, respond quickly when something reaches an inbox, and recover data when prevention alone is not enough.
the problem
Today's email attacks are built to look ordinary
Spam and known malware are the easy part. Standard filtering handles those well. Some of the most damaging attacks, spear phishing, business email compromise, domain impersonation, and account takeover, are built specifically to look like a normal message from someone your team already trusts.
These are targeted, low-volume, and quiet. There is often no obvious red flag, which is exactly why they get through gateway filtering that is tuned to catch bulk threats.
A quick gut check:
- Would you know if someone was sending fraudulent email that appeared to come from your own domain
- If an employee's mailbox were compromised today, would anything catch it before it was used to attack your other contacts
- If a malicious email reached ten inboxes this morning, could you find and remove every copy without checking each one by hand
If any of those feel uncertain, that uncertainty is the gap this service closes.
why it works
No single layer catches everything
A gateway filter is very good at evaluating the message itself: known malware signatures, blacklisted senders, obvious spam patterns. More sophisticated attacks call for another layer, one that can also consider who is communicating, what is normal for that person, and whether the request fits their usual behavior.
That is why this service combines gateway defense with behavioral detection after delivery, so protection does not stop the moment a message is delivered. If something still gets through, automated response and backup limit how much damage it can do.
what's included
What the service includes
The service is built around four stages: prevent what can be stopped at the gate, detect what makes it through, respond quickly when something reaches an inbox, and recover data when prevention alone is not enough.
Prevent
Email Gateway Protection
Filters spam, known malware, and email-borne viruses before they reach an inbox, with no hardware or software required on your end.
Zero-Day Attachment Sandboxing
Unknown attachments are detonated in an isolated cloud environment to observe their behavior before they ever reach a user, catching threats that do not match a known signature.
Malicious Link and Typosquat Protection
Suspicious and lookalike URLs are checked and blocked at the moment they are clicked, including domains built to imitate a trusted site.
Outbound Filtering and Encryption
Outbound mail is screened for botnet activity and sensitive data, with automated encryption available to protect anything leaving your organization.
Detect
Behavioral Threat Detection
Analyzes communication patterns to establish what normal email activity looks like for each user, then flags messages that fall outside it, catching attacks built to slip past standard filtering.
Domain Fraud Monitoring
Runs as a separate layer that monitors how your domain is being used across the internet, helping identify unauthorized senders and attempts to impersonate your company.
Account Takeover Detection
Watches for anomalous mailbox behavior that signals a compromised account, and moves to contain it before it can be used to launch attacks internally or against your contacts.
One-Click Employee Reporting
An Outlook add-in lets employees flag a suspicious email for review the moment they see it, without leaving their inbox.
Respond
Automated Incident Response
Once a threat is confirmed, every copy of it is located and removed from every mailbox it reached, including messages that arrive after the initial response.
Affected-User Notification
Anyone who received or interacted with a malicious email is automatically notified, along with the steps needed to secure their account.
Xentric Review and Escalation
Incidents that call for judgment, not just automation, are reviewed by our team, who decide what action is needed and follow up directly.
Recover and preserve
Preventing a malicious email is one problem. Recovering from deleted, encrypted, or corrupted Microsoft 365 data is another. The service also includes independent backup and archiving as a recovery path for when prevention alone is not enough.
Cloud-to-Cloud Backup for Microsoft 365
Gives you an independent copy of Exchange Online, SharePoint, OneDrive, and Teams data, so deleted or corrupted information can be recovered without depending entirely on Microsoft’s native retention.
Compliance-Ready Archiving
Keeps a searchable, retained copy of email for e-discovery, legal hold, and audit requests, with retention policies that stay consistent even after an employee leaves.
the differentiator
Detection that learns how your business communicates
Most email attacks that succeed today are not sloppy. They are researched, personalized, and written to sound exactly like a message your team would expect.
Rather than relying only on known threat signatures, the detection layer analyzes communication patterns to establish what normal email activity looks like for each user. When a message or interaction falls outside those patterns, such as an unusual sender, request, or account behavior, it can be flagged for review in real time, without waiting for someone to notice something felt off.
Domain fraud monitoring works differently. It runs as a separate layer that watches how your company's domain is being used across the internet, helping catch spoofing and impersonation attempts before they damage a relationship with a client or vendor.
built for how you work
Protection that runs in the background
The service is cloud-based, so there is no hardware or software for your employees to install. Gateway protection works transparently in your existing mail flow, while the detection layer connects directly to Microsoft 365 to monitor messages after delivery.
Your team keeps using Outlook and the rest of Microsoft 365 exactly as they do now. The security happens around them, without giving employees another system to manage or slowing down day-to-day email.
When action is needed, it happens automatically. When a decision calls for judgment, our team reviews it. Either way, it does not fall on your staff to manage.

Can someone easily spoof your email domain?
SPF, DKIM, and DMARC help prevent attackers from sending email that directly impersonates your domain. Missing or misconfigured records can make that kind of spoofing much easier. They are an important part of email security, but they do not stop lookalike domains, compromised accounts, or other forms of impersonation. Check your domain below to see whether this foundational layer is configured correctly.
DKIM selectors are chosen by your mail provider, so we check common ones automatically. A miss there doesn't necessarily mean DKIM is missing.

PendingDKIM
PendingDMARC
PendingThis checks the domain-authentication layer of your email security. It does not evaluate mailbox protection, account compromise, lookalike domains, phishing detection, or incident response.

Backup, archiving, and staying ready for the questions that come up
Preventing a malicious email is one problem. Recovering from deleted, encrypted, or corrupted Microsoft 365 data is another, and it does not require an attack to happen.
Cloud-to-cloud backup gives you an independent copy of Exchange Online, SharePoint, OneDrive, and Teams data, so deleted or corrupted information can be recovered without depending entirely on Microsoft's native retention. Email archiving keeps a searchable, retained copy of your mail for e-discovery, legal hold, and audit requests, with retention policies that stay consistent even after an employee leaves.
Cyber insurance applications and renewals increasingly ask businesses about email security controls, backup, multi-factor authentication, and security awareness training. Having those controls in place, and documented, makes those questions much easier to answer.
why xentric
A protection platform is not the same thing as a managed service
Advanced email protection is not something you buy once and forget. Policies need to stay tuned to how your business actually operates. Alerts need to be reviewed, false positives understood, and real threats need someone to respond. As your business changes, the protection needs to change with it.
Email security is also one layer of XenSecure. It works best coordinated with the rest of your protections, including identity protection, multi-factor authentication, endpoint security, and security awareness training.
That coordination is where Xentric comes in. As part of XenSecure, we handle setup, tune detection to your business, review and respond when something is flagged, and keep this service working alongside the rest of your security, instead of sitting as another disconnected tool.
