Crestline Technologies helps East Tennessee businesses protect users, secure Microsoft 365, strengthen endpoint defenses, reduce email risk, plan for incidents, and support compliance-related IT requirements without juggling multiple vendors.
A Managed Security Service Provider (MSSP) helps manage the security controls that go beyond day-to-day IT support: endpoint detection, email security, identity hardening, alert review, and incident response planning.
Many small businesses in East Tennessee still rely on basic antivirus and hope nothing slips through. That leaves Microsoft 365 accounts, remote access, backups, and user devices exposed.
Crestline Technologies builds layered security for Knoxville and East Tennessee SMBs: endpoint protection, identity management, email controls, security monitoring options, and compliance-aware documentation sized for your team.
Start With a Security Assessment →A breakdown of each security service area Crestline Technologies delivers — what it includes, why it matters, and what your team can expect.
Practical IT support for organizations with HIPAA, CMMC/NIST 800-171, PCI DSS, or other security-driven requirements. Crestline helps with technical safeguards and documentation support without claiming to certify compliance.
Systematic identification of vulnerabilities across your network, systems, and applications — before attackers find them. Our assessments produce prioritized remediation plans, not just lists of findings.
Monitoring options for endpoint, identity, network, and Microsoft 365 alerts. Crestline helps tune signals, review alerts, and escalate real issues so your team is not sorting through noise alone.
Most breaches start with a compromised identity. We implement and manage the controls that limit what a stolen credential can actually do — MFA, conditional access, and privileged account governance.
Protecting data at rest and in transit, including classification, DLP configuration, sensitivity labels, and practical safeguards for HIPAA-aware and PCI-focused environments.
Most attacks still start in the inbox. Crestline helps harden Microsoft 365 email, reduce phishing risk, and train users to spot common social engineering attempts.
When a security incident occurs, speed and structure determine how much damage is done. We provide both proactive planning and active incident response — from containment through forensic analysis and post-incident hardening.
Layered protection for user devices and network access, including endpoint detection, firewall hardening, segmentation, and mobile device controls for supported environments.

Based on your answers, here are common security and compliance areas to review with your internal leadership, counsel, auditor, or assessment partner:
A consultation can help identify technical gaps, backup risks, Microsoft 365 concerns, and documentation that may need attention.
Schedule a Compliance-Aware IT ReviewWhether onboarding a new managed security client or responding to a specific compliance-related requirement, our process follows a practical four-phase structure.
A focused assessment of your current security posture: network discovery, vulnerability review, access control review, Microsoft 365 settings, backup posture, and gaps against applicable technical requirements. You receive written findings with prioritized risk ratings before remediation work begins.
Assessment findings become an actionable remediation roadmap: a prioritized list of controls, policy updates, and technical changes with timelines and effort estimates. For CMMC/NIST-related work, this may support an SSP or POA&M maintained by the business.
We execute the remediation plan by deploying technical controls, documenting changes, training staff, and coordinating improvements in a way that avoids disrupting business operations.
Security is not a one-time project. Ongoing clients can receive alert review, vulnerability checks, Microsoft 365 and endpoint hardening, backup risk review, and regular reporting on security improvements and open items.
You get practical security help from the same East Tennessee team that understands your users, devices, Microsoft 365 setup, backups, vendors, and business priorities.
Local security engineers who know East Tennessee industries — and show up on-site when something goes wrong instead of opening another remote ticket.
Managed clients have response expectations defined by agreement and severity, with a clear path for escalating security incidents, backup concerns, and account compromise risks.
We help translate technical requirements into practical controls, documentation, and operational steps while avoiding promises no IT provider should make on compliance outcomes.
