For a technology company whose business is built around artificial intelligence and digital transformation, maintaining a strong, efficiently managed cybersecurity environment is essential. But as SESTEK’s technology environment evolved, its existing security approach was becoming increasingly difficult for its IT team to manage.

Challenge

For many years, SESTEK’s cybersecurity strategy relied primarily on network firewall and antivirus technologies. However, as cyber threats grew more sophisticated, the company recognized that its infrastructure no longer provided the level of protection, visibility, and operational efficiency it required.

Managing separate security products created unnecessary complexity for the IT team. In addition, network visibility and threat detection were limited, incident response could take too long, and managing security devices across locations added additional operational overhead. Implementation of MFA and improved identity and credential protection were top concerns. At the same time, SESTEK needed to meet regulatory and compliance requirements while controlling licensing and operating costs.

These challenges were particularly important for a company with limited IT resources. SESTEK’s team is responsible for a broad range of functions, from network and endpoint security to patch management, inventory, remote connectivity, and reporting. The company needed an approach that could strengthen security without requiring additional dedicated personnel to manage every individual security discipline.

When evaluating alternatives, SESTEK prioritized three requirements: security effectiveness, ease of management, and total cost of ownership. The company also evaluated advanced threat prevention, visibility into network and user activity, centralized reporting, scalability, high availability, secure remote access, integration with its existing infrastructure, technical support, and independent security performance.

Solution

SESTEK selected WatchGuard because it could bring multiple layers of cybersecurity together while simplifying how its IT team operated.

WatchGuard Firebox M590 and M390 appliances provide network security and advanced threat prevention, including firewall, intrusion prevention, URL filtering, and application control. WatchGuard Endpoint Security 360 offers advanced EDR with deny-by-default protections, while Patch Management helps SESTEK address vulnerabilities and maintain systems. AuthPoint MFA strengthens authentication and remote-access credential security through its integrated identity management capabilities and an easy-to-use MFA client application. WatchGuard Cloud provides centralized management, monitoring, and reporting across all WatchGuard products, unifying solutions in a single location that the company had previously lacked.

The integrated approach was an important differentiator. Instead of continuing to manage network, endpoint, identity, and security operations as disconnected technologies, SESTEK could consolidate visibility and management across its security environment.

According to SESTEK, the implementation was straightforward. The WatchGuard interface and documentation enabled its team to learn the platform quickly, with initial setup and policy configuration completed faster than expected. Support and training from WatchGuard and its partner further simplified the transition.

Most importantly, the solution addressed both sides of SESTEK’s challenge: improving cybersecurity while reducing the operational burden placed on a limited IT staff.

Results 

With WatchGuard in place, SESTEK has significantly improved the visibility and manageability of its security infrastructure. Centralized monitoring and reporting give its IT team greater insight into security activity and enable potential threats to be detected and addressed more quickly.

The operational impact is equally important. Processes that previously required multiple security tools are now managed through a more unified environment, reducing complexity and enabling SESTEK to make more effective use of its existing IT resources. The company reports faster response times for security incidents, increased security team efficiency, more secure remote access and authentication, and improved network performance and system availability.

For SESTEK, that efficiency translates directly into business value. Their IT team no longer needs dedicated resources for every individual cybersecurity function. WatchGuard helps the team manage network security, endpoint protection, patching, secure remote access, authentication, monitoring, and reporting while maintaining a stronger overall security posture.

SESTEK is also looking ahead. As its security strategy evolves, the company plans to evaluate WatchGuard XDR and MDR services to provide even broader detection, response, and managed security operations.

Why It Matters

For SESTEK, the biggest benefit isn’t simply deploying more security technology. It’s about delivering stronger cybersecurity with the team it already has.

By bringing network, endpoint, identity, patch management, visibility, and reporting together, WatchGuard has helped SESTEK reduce operational complexity while improving protection, giving its IT team more time to focus on the technology and business priorities that drive the company forward.
