Managed Cybersecurity Services in Houston, TX

Layered, 24/7 defense for SMBs — built and run by Conroe-based engineers and SOC analysts. EDR, NGFW, NAC, IAM/MFA, email security, and incident response under one flat monthly agreement.

Eight Layers of Defense. One Flat Monthly Fee.

Modern attackers don’t kick down the front door — they slip in through a phishing email, an unpatched laptop, or a stolen password. A real cybersecurity program covers every layer where they try to get in, not just one. Galaxy IT’s managed cybersecurity stack runs eight coordinated defenses for you, monitored 24/7 by our Houston SOC.

End-User Security Awareness Training

Your users are your first line of defense — and the most-attacked one. We run continuous awareness training plus monthly simulated phishing campaigns so your team learns to spot real attacks before they cause damage.

  • Short, video-based modules — 4 to 8 minutes each
  • Monthly simulated phishing emails tailored to your industry
  • Per-user risk scoring and remedial training auto-assigned
  • Reports for HIPAA, PCI, CMMC, and SOC 2 evidence

Email Threat Protection

91% of breaches start with email. We layer advanced email security in front of your Microsoft 365 or Google Workspace tenant to block phishing, business email compromise, malware, and credential-theft attempts before they hit an inbox.

  • AI-based phishing and BEC detection
  • URL rewriting and time-of-click scanning
  • Attachment sandboxing for unknown files
  • DMARC, SPF, and DKIM configuration and monitoring
  • End-user spam quarantine and self-service release

Endpoint Protection — EDR/MDR

Traditional antivirus catches yesterday’s malware. We deploy enterprise-grade EDR (Endpoint Detection and Response) backed by 24/7 MDR analyst review — every alert is investigated by a human before you ever hear about it.

  • Behavioral detection — not signature-based AV
  • Ransomware rollback on Windows endpoints
  • 24/7 SOC triage and active response
  • Process tree forensics and root-cause analysis
  • Coverage for Windows, macOS, Linux servers

Next-Generation Firewall (NGFW)

Your perimeter firewall does more than block ports. We deploy and manage Palo Alto, Fortinet, or Meraki next-generation firewalls with full Layer 7 inspection — apps, users, and threats, not just IP addresses.

  • Application-aware filtering (block TikTok, allow Teams)
  • IPS/IDS with daily threat-feed updates
  • TLS / SSL decryption with privacy exclusions
  • DNS sinkholing for command-and-control domains
  • Geo-IP blocking and country-level policy
  • Site-to-site and remote-access VPN

Network Access Control at the Port Level

A rogue device plugged into a wall jack should not get on your network. We implement 802.1X port-based access control — every device authenticates before it touches a single packet, and unknown devices land on a quarantine VLAN.

  • 802.1X with certificate or credential auth
  • Dynamic VLAN assignment by user/device role
  • MAC Authentication Bypass (MAB) for printers/cameras
  • Guest network isolation
  • Posture checks — OS patched, EDR running, disk encrypted
  • Cisco ISE, Aruba ClearPass, or Fortinet FortiNAC

Identity Access Management & MFA

Stolen passwords are the #1 way attackers get in. We harden your identity layer — Microsoft Entra ID (Azure AD), Conditional Access, and phishing-resistant MFA — so a leaked password alone never gets anyone into your environment.

  • MFA on every cloud and on-prem account
  • Conditional Access — block risky logins by geography, device, app
  • Privileged Identity Management (PIM) for admin roles
  • Passwordless and FIDO2 hardware key rollouts
  • Just-in-time admin access with approval workflow
  • Quarterly access review and dormant-account cleanup

Disaster Recovery & Ransomware-Resistant Backup

When prevention fails, recovery is what saves the business. We design and operate backup and DR programs with documented RPO/RTO, immutable cloud copies, and quarterly restore testing — so a ransomware event becomes a bad afternoon, not a closure.

  • Image-based server backups with 30-day local + cloud retention
  • Microsoft 365 backup (Exchange, SharePoint, OneDrive, Teams)
  • Immutable cloud copies — ransomware cannot delete them
  • Quarterly restore tests with documented results
  • DR runbooks per critical system
  • Defined RPO/RTO targets in your service agreement

Process Control & Incident Response

Tools without process is just expensive software. We document your security program, define who does what when an alert fires, and stand ready as your IR team if something gets through. Same-day engagement for active incidents.

  • Written incident response plan and tabletop exercises
  • NIST CSF-aligned policies and procedures
  • 24/7 SOC monitoring with SLA-backed escalation
  • Same-day IR engagement for ransomware, BEC, breach
  • Evidence chain-of-custody for legal and insurance
  • Post-incident report and lessons-learned review

What This Looks Like Day-to-Day

You won’t see most of what we do — and that’s the point. While your team is working, our SOC is:

  • Reviewing EDR alerts and quarantining suspicious processes
  • Tracking failed-MFA spikes and impossible-travel logins
  • Patching the Chrome zero-day announced this morning
  • Reviewing weekly phishing simulation results and assigning training
  • Validating last night’s backup restore
  • Updating firewall threat feeds and blocking new C2 domains

Every quarter we sit down with you for a Business Review — what we caught, what changed, what’s next, and where your risk score moved.

Audit-Ready by Design

Every control above produces evidence — logs, screenshots, policy docs, restore test reports. We collect it continuously so audit week stops being a fire drill.

Managed Cybersecurity — Frequently Asked Questions

Is this an MDR service or just tools?

Both. The EDR/MDR layer is monitored 24/7 by our Houston-based SOC analysts — we triage every alert before it ever reaches you, and we contain active threats in real time. Tools without a human reviewing them are just expensive logs.

Do we have to rip and replace our existing security tools?

Usually not. We assess what you already own (firewalls, EDR, M365 Defender, backup) and tune what's working before recommending swaps. The goal is the strongest stack we can build with as little change as possible.

Can you work with our existing Palo Alto / Fortinet firewalls?

Yes. We're a Palo Alto and Fortinet partner and our engineers hold both PCNSE and NSE certifications. We can either co-manage your existing devices or migrate to our managed-firewall offering, whichever makes sense.

What happens if we get hit with ransomware right now?

Call (346) 406-1700 immediately. We have an incident response retainer option and can engage same-day for active ransomware, business email compromise, and data breaches. EDR rollback can sometimes contain it during the call.

How is this priced?

Managed cybersecurity is included in our standard managed services bundle at $149 per user per month — EDR/MDR, email security, DNS filtering, phishing simulation, and patch management are baseline. Add-ons (advanced compliance evidence, dedicated SOC analyst, full NAC deployment) are quoted separately.

Can we just buy cybersecurity without your full IT managed services?

Yes. Many clients start with managed cybersecurity (EDR/MDR + email + SOC) before moving to full managed IT. We'll be honest about which makes sense for your size, risk profile, and budget.

Will you give us a vulnerability scan and a security posture report?

Yes — every onboarding includes a baseline external and internal vulnerability scan, an M365 configuration review (Microsoft Secure Score), and a written report with prioritized remediation. We share the report whether you sign with us or not.

Get a no-pressure security posture review.

We’ll run an external scan, review your M365 Secure Score, and give you a written report with the top 5 things to fix — yours to keep whether you hire us or not.
