Managed IT & Helpdesk — Southern California
Security first. Accountable by design.
For over 25 years, TNS has managed the technology behind Southern California businesses. Our managed IT service combines a remote-first help desk, proactive monitoring, endpoint and infrastructure management, Microsoft 365 administration, and a managed cybersecurity stack watched around the clock — brought together into one accountable service relationship, with a named team that knows your environment.
Four pillars of managed IT.
Remote help desk & user support
A remote-first help desk your team can reach by portal, email, or phone. Most issues are resolved remotely, which means faster response and less disruption.
- Business-hours remote support for covered users
- Password resets and routine account assistance
- Microsoft 365, Windows, email, printing, and connectivity
- Tiered escalation to systems and network engineers
Endpoint & infrastructure management
Continuous monitoring and management of the devices and systems your business runs on, with automated remediation where it makes sense.
- Remote monitoring and management of covered endpoints
- Device health, disk, service, and performance monitoring
- Server and network-device availability monitoring
- Automated remediation where appropriate
Microsoft 365 administration
Day-to-day administration of your Microsoft 365 environment, from users and licensing to security configuration.
- User, mailbox, group, and license administration
- MFA and Conditional Access management
- Exchange Online, Teams, SharePoint, and OneDrive
- Security and configuration administration
Documentation & strategic guidance
Your environment documented and kept current, plus regular reviews that keep technology aligned with where your business is going.
- Asset and configuration documentation
- Credential and vendor information management
- Quarterly business reviews
- Technology roadmap and lifecycle recommendations
Cybersecurity that's managed, not just licensed.
Most providers list "cybersecurity" as a single line item. We break out exactly what we deploy, what each control stops, and who's watching it — backed by a 24/7/365 security operations center that validates alerts before they reach us.
Managed Endpoint Detection & Response (EDR)
Behavior-based endpoint protection on every covered workstation and server — catching attacker activity that traditional antivirus misses, with human-validated alerts around the clock.
Identity Threat Detection & Response (ITDR)
Identity threat detection for Microsoft 365. MFA is necessary but no longer sufficient; this watches the identity layer for stolen-session and account-takeover attacks that bypass it.
Email & Collaboration Security
Advanced email security that works inside Microsoft 365 — catching phishing and business-email-compromise, and pulling malicious messages from every inbox they reached, even internal ones.
Patch & vulnerability management
A measured, reported patch program with pilot-ring testing, enforced reboots, expedited handling of actively exploited vulnerabilities, and compliance reported by device class.
What you get with Managed IT & Helpdesk.
A named team, not a queue
You're introduced to your assigned engineers and account lead at kickoff, and they stay with your account. You won't re-explain your environment every time you call.
24/7 security operations
A security operations center triages and human-validates alerts across endpoint and identity around the clock, so threats are caught and contained — not left in a console for you to interpret.
Proactive monitoring
Endpoint, server, and network monitoring runs continuously. Work often begins before you even notice a problem, rather than starting when you place a call.
Measured patch management
Patching is ringed, enforced, measured, and reported — with expedited handling for actively exploited vulnerabilities. Patch compliance has a number as its answer.
Transparent scope
What's included, what's quoted, and what's billed hourly is written down before you sign — not discovered on an invoice later.
Reporting you can act on
Ticket volume and response performance, patch compliance, backup success, and security events — reported and reviewed with your leadership at quarterly business reviews.
Simple to get started.
Kickoff & discovery
We meet your named account team, collect documentation and credentials, discover your environment, and coordinate with your outgoing provider — so support is informed from day one.
Deploy & secure
We deploy monitoring and security agents, establish your MFA and Conditional Access baseline, begin patch cycles, and open your support channels and ticketing.
Stabilize, optimize & review
We resolve inherited issues, tune security, complete documentation, and deliver your first quarterly business review with a technology roadmap for the next 12–24 months.
When it's urgent, we treat it that way.
Not every issue is equal. We prioritize by impact, so a server outage never waits behind a routine request.
Response time is time to initial engagement, not resolution. These are objectives, not guarantees, unless defined in a formal SLA. Coverage: Monday–Friday, 7:00 AM–7:00 PM Pacific, with monitoring and critical response 24/7/365.
Three ways to reach support.
What this means for your business.
- Less downtime and fewer daily disruptions
- Stronger, continuously monitored security posture
- Predictable, well-documented, well-patched systems
- One accountable partner for all of IT
