Cybersecurity Services St. Louis Businesses Need
This page explains Inzo’s cybersecurity services for St. Louis businesses and how to discuss your protection needs with our team.
What are cybersecurity services?
Cybersecurity services are tools and practices that protect computers, user accounts, email and networks from digital threats. Inzo helps St. Louis businesses reduce exposure to malicious software, stolen credentials and fraudulent messages through managed protection for devices, identities, email and web access.
Who delivers your cybersecurity services?
Inzo Technologies is headquartered in Chesterfield, Missouri, and brings IT support, cybersecurity, healthcare technology and business communications together in one team. The company began as STL Communications in 1989. Read about Inzo's history and leadership.
Our protection services cover devices, identities, email and web access. Security operations adds investigation and response through a U.S.-based Security Operations Center. Backup and recovery addresses how you restore data and resume work. Confirm the responsibilities and coverage for each in your service scope.
How layered cybersecurity protects a small business
A reused password, a malicious email or an unpatched device can create an opening. Layered protection combines controls across those entry points with monitoring and response. No single tool covers every risk.
What our cybersecurity protection stack covers
Inzo Technologies® protects the four layers attackers target most: the devices your team uses, the accounts they log in with, the email they receive, and the websites they connect to.
Endpoint detection and response
Traditional antivirus catches threats it already recognizes. Endpoint detection and response (EDR) watches how programs behave to help detect and contain ransomware and other malicious activity. When a device shows signs of compromise, automated isolation and investigation help limit the spread.
Account and identity protection
Attackers log in far more often than they break in, using passwords stolen or reused from other breaches. Multi-factor authentication (MFA) makes a stolen password useless on its own. Enterprise password management gives your team strong, unique credentials without spreadsheets or sticky notes. We also watch for signs of account takeover so we catch compromise early.
Email security and business email compromise prevention
Email is still where most attacks start. A fake message from your CEO requesting an urgent wire. A vendor sending new banking details right before a payment goes out. Our email security analyzes senders, language patterns, look-alike domains, and embedded links to catch these before they reach an inbox. Business email compromise (BEC) ranks among the most expensive attacks we see and the most preventable.
Web and DNS filtering
Every website visit starts with a Domain Name System (DNS) lookup that translates the address. DNS filtering intercepts that lookup and blocks known malicious destinations, so phishing pages never load and malware cannot reach the servers controlling it. This layer catches threats that slip past the others.
Microsoft 365 security depends on configuration and monitoring
Microsoft 365 Business Premium, E3, and E5 include real security capabilities. The outcomes depend on correct configuration, continuous monitoring, and response when alerts fire. We configure what you already own, integrate it with the rest of the program, and add the monitoring and response that turn licensed tools into working protection.
How protection connects to a Security Operations Center
Prevention catches most attacks. Detection and response cover the rest. Every tool on this page feeds a U.S.-based Security Operations Center (SOC), where trained analysts watch your environment, investigate what looks suspicious, and take action before a small signal becomes a serious incident.
How protection fits the bigger picture
Protection is one layer of a larger program. Defending devices, accounts, email, and web activity works best when paired with monitoring, recovery, and a team that runs the whole environment.

Cybersecurity services: common questions
The four layers attackers target most: the devices your team uses (endpoint detection and response), the accounts they log in with (multi-factor authentication, enterprise password management and account takeover monitoring), the email they receive (email security and business email compromise prevention), and the websites they connect to (web and DNS filtering).
Traditional antivirus catches threats it already recognizes. Endpoint detection and response (EDR) watches how programs behave, so it can stop ransomware and newer attack techniques as they execute. When a device shows signs of compromise, it is isolated and investigated before damage spreads.
Microsoft 365 Business Premium, E3 and E5 include real security capabilities, but the outcome depends on correct configuration, continuous monitoring and response when alerts fire. We configure what you already own and add the monitoring and response that turn licensed tools into working protection.

Business email compromise (BEC) is a fraudulent message that impersonates someone you trust: a fake request from your CEO for an urgent wire, or a vendor sending new banking details right before a payment. Email security analyzes senders, language patterns, look-alike domains and embedded links to catch these before they reach an inbox.
