Email Security in Humble
Email is still where most losses start: a fake invoice, a spoofed vendor, a login page that looks right. Email security means filtering, sender authentication, encryption, and attachment inspection configured properly and then kept that way.
The Problem
The attack that costs a Humble company real money is rarely dramatic. A freight forwarder receives updated wire instructions that appear to come from an existing carrier, and accounting pays them. A clinic front desk clicks a shared document link and hands over a password that also unlocks the records system. Most businesses run mail on Microsoft 365 or Google Workspace with default settings, no published sender authentication, and no inspection of attachments beyond a virus signature. Meanwhile anyone can send mail that appears to come from your own domain, because SPF, DKIM, and DMARC were started and never finished.
The Solution
Sentinel-Pros hardens the mail platform you already own, then layers filtering that reads intent and context instead of only known bad files. We publish and enforce sender authentication so your domain cannot be impersonated, sandbox attachments before delivery, and flag lookalike domains that differ from a real vendor by a single character. Encryption is configured for the messages that need it, such as patient information or contract documents. The work is remote end to end, though Humble is inside our on-site area when a session with your accounting staff is better held in person. We also watch for the mailbox rules attackers create after a successful login.

Protecting What Leaves
Engagement Process
Mail Audit
We review your tenant configuration, sender records, filtering policy, and every mail rule already in place. Most audits turn up forwarding rules or legacy connectors that nobody remembers creating.
Harden the Platform
Legacy authentication is switched off, filtering policy is rebuilt to a known standard, and multi-factor is enforced on every mailbox, including shared and service accounts that are usually skipped.
Authenticate the Domain
We publish sender records, read the reports they generate, fix the legitimate senders they expose, and only then move to enforcement so spoofed mail is rejected outright.
Watch and Adjust
Filtering, quarantine review, and rule monitoring continue as an operated service, with tuning as your vendors and workflows change. Pricing is a fixed monthly retainer scoped on a discovery call.

Common Questions
Microsoft already filters our mail. Why add anything?
The built in filtering catches most bulk spam and known malware. It is far weaker on a targeted message with no attachment and no link, which is what business email compromise usually looks like. We tune the native controls first and add layers only where a real gap remains.
Will enforcing DMARC stop our own mail from being delivered?
Not if it is done in the right order. We publish records in monitoring mode first, read the reports to find every legitimate service sending on your behalf, fix those, and then move to enforcement. Skipping the monitoring stage is how companies break their own invoices and appointment reminders.
A vendor emailed us new bank details last month. How do we avoid paying the wrong account?
Technology helps and process finishes the job. Filtering and lookalike domain alerts catch many of these before they land. Alongside that we help you set a standing rule that any banking change is verified by phone to a number already on file, never a number printed in the message.
We handle patient information. Does this cover encryption?
Yes. We configure encryption for outbound messages carrying protected health information, and set rules that catch it when a staff member forgets. That is one component of a broader HIPAA posture, and we will tell you plainly where the rest of your gaps are rather than implying email alone gets you there.
What happens when someone does click?
We revoke the session, force a password reset, check for mailbox rules and forwarding the attacker added, and look at any mail already sent from the account. Then you get a written account of what was reached. If it turns out to be larger than one mailbox, it moves into our incident response process.

BOOK A CONSULTATIONEmail Security for Humble, Texas
Payment fraud by email lands hardest on businesses that move money against paperwork, and northeast Houston is full of them. Freight forwarders and customs brokers working George Bush Intercontinental Airport process carrier invoices, duty payments, and charges from partners they may never meet in person, which is precisely the environment where a spoofed message carrying new remittance details succeeds. Homebuilders and trade contractors across Kingwood, Atascocita, and the Lake Houston corridor pay subcontractors on draw schedules, and a redirected draw is money that does not come back. Medical practices near Memorial Hermann Northeast send referrals, imaging, and records by email daily, so one compromised mailbox becomes a reportable disclosure of patient information rather than an inconvenience. Retailers around Deerbrook Mall field vendor and landlord correspondence with seasonal staff who have not been around long enough to know which requests are normal. Humble businesses also tend to run lean back offices, where the same person opens the mail, approves the invoice, and releases the payment, which removes the second set of eyes that catches these attempts elsewhere. Sentinel-Pros configures and operates the mail defenses remotely, and because Humble is in our on-site service area we can sit down with your accounting staff in person when the real fix is as much about process as it is about filtering.
