The castle-and-moat security model is dead. Houston enterprises operating with hybrid workforces, multi-cloud environments, and distributed branch offices need an identity-first, zero-trust architecture where nothing is trusted by default ā inside or outside the network perimeter. xS IT designs and deploys Zero Trust Network Access (ZTNA) that eliminates lateral movement, stops insider threats, and gives you complete visibility into every user, device, and application.
26 years of veteran-led IT expertise, applied specifically to the challenges, compliance requirements, and operational realities of mid-market and enterprise organizations in the Greater Houston area.
Okta, Entra ID, or Ping Identity deployment with adaptive multi-factor authentication, conditional access policies, and privileged identity management ā making compromised credentials useless without a verified device and context.
East-west network traffic segmentation using Illumio, Guardicore, or VMware NSX that contains breaches to the single workload they started in ā preventing the lateral movement that turns a single compromised endpoint into a full data breach.
Secure Access Service Edge (SASE) deployment converging SD-WAN with cloud-native security (Zscaler, Netskope, Palo Alto Prisma) ā providing consistent zero-trust policy enforcement for users in any location accessing any cloud application.
UEBA (User and Entity Behavior Analytics) with baseline behavioral profiles for every user and device ā automatically detecting anomalies like impossible travel, credential harvesting, and data exfiltration without waiting for a SIEM alert.
Hardened privileged access workstations (PAWs), just-in-time privileged access, and session recording for all administrative actions ā eliminating the privileged account abuse that drives 74% of enterprise breaches.
Conditional access policies enforce device compliance before granting application access ā ensuring only patched, enrolled, policy-compliant devices can reach sensitive corporate resources regardless of network location.
From discovery through ongoing management, our process is designed to deliver measurable results at every phase ā with zero disruption to your operations.
We assess your current security architecture against the CISA Zero Trust Maturity Model across five pillars: Identity, Devices, Networks, Applications, and Data ā producing a scored maturity roadmap with quick-win recommendations.
A phased Zero Trust architecture blueprint tailored to your cloud footprint, application portfolio, workforce distribution, and risk profile ā with technology selections, integration specifications, and a deployment timeline.
Deployment begins with identity (highest impact, fastest win) and progresses through device trust, network segmentation, application access, and data protection ā in coordinated phases that deliver security value at each stage.
Ongoing policy management, anomaly investigation, quarterly access reviews, annual architecture reviews, and adaptation to emerging threats ā with a dedicated xS security engineer who knows your environment as well as you do.
"After a lateral-movement incident that started with a phishing email and spread to 40 systems before we caught it, we engaged xS IT to design our zero-trust architecture. 18 months later, a pen test showed that same phishing attack would now be contained to a single workload. The attackers have nowhere to go."ā Houston Enterprise CISO | xSā¢ IT Consulting ā Veteran Family Founded and Operated
