Local, responsive, on‑site when needed.
Dallas coverage with the convenience of remote support and the reassurance of in‑person help.
Protection that fits the way your business works—designed, delivered, and supported by
a Dallas managed security provider you can reach on the first call.
Cyber threats evolve daily, insurers tighten underwriting, and internal teams are stretched. Sagiss makes managed IT security simple for Dallas organizations by combining right‑sized controls with around‑the‑clock monitoring and pragmatic guidance. You get fewer phishing incidents, faster patch compliance, documented controls for audits and cyber‑insurance, and the confidence that backups and response plans are tested before you need them.
If you’re comparing cybersecurity services or searching for a Dallas managed security provider, our approach delivers strong protection without enterprise‑level complexity.
Security shouldn’t slow you down. We harden what matters first—identity, email, endpoints, networks, and recovery—then monitor continuously so your posture improves month after month.
Whether we co‑manage alongside your IT team or operate as your dedicated security partner, we align controls to your environment and budget so protection scales as you grow.
These are the services that harden your environment and keep threats in check.

Managed endpoint detection and response for Windows and macOS with 24/7 alerting, triage, and remediation.

At Sagiss, our managed security services are designed around the way your business actually operates, not around generic tools or one-size-fits-all solutions. We combine proactive defense, real-time monitoring, and strategic guidance to keep you protected today and prepared for tomorrow.
Let’s take the next step together
Here you’ll find answers to the most common questions about our Managed Cloud Services. These insights will help you understand how Sagiss supports your business in the cloud.
We can co-manage with your team or serve as your dedicated security provider. It’s your choice. Up front, we define clear handoffs so roles are understood and nothing slips through the cracks.
We focus on Microsoft 365/Entra ID, Windows and macOS endpoints, modern next-gen firewalls, leading EDR, and reputable backup/DR platforms. We’ll work with your current stack or recommend right-sized tools that fit your goals and budget.
Our program aligns to common underwriting requirements—MFA, EDR, backups, patching, and documented response plans. We help map controls, close gaps, and provide the evidence you’ll need at renewal, while acknowledging each carrier’s specifics.
We begin with a focused discovery to understand your environment and priorities. From there, we deploy security tools and baseline policies, verify monitoring, and address the most important gaps first. Early check-ins keep everyone aligned, and you’ll leave onboarding with clear visibility into your posture and a practical improvement plan.
All endpoints and identities are continuously monitored by our 24/7 SOC, and our on-call team—staffed by Sagiss employees—is available around the clock to respond. When an incident occurs, we move quickly to assess, contain, and guide remediation across identity, email, endpoint, and network layers. After resolution, we strengthen controls, document lessons learned, and, in severe cases, coordinate with forensics and legal teams as needed.
