Working with Nessit for the past 5 years has been one of my best vendor experiences. They are incredibly proactive, often resolving issues before we even notice them. What truly sets them apart is their knowledgeable team; they have a rare ability to explain complex technical problems in plain English.
Nessit doesn’t just wait for tickets—they actively look for ways to take work off my plate and streamline our processes. By taking full ownership of our infrastructure and always volunteering to take on more responsibility, they’ve completely removed the ‘IT burden’ from my daily routine. I can’t recommend them enough.

What's Included in Managed Detection & Response (MDR)

Proactive protection and expert response

Nessit’s 24/7 Security Operations Center (SOC) delivers continuous monitoring and rapid threat response. Dedicated security professionals analyze alerts in real time, allowing issues to be contained before they escalate. This always-on vigilance means potential breaches are identified within minutes, minimizing risk to your business. The SOC also provides detailed incident reports and recommendations for ongoing improvements, supporting your compliance and audit needs.

Advanced Endpoint Detection and Response (EDR) is included for all MDR clients, ensuring robust protection for every device. Nessit’s EDR systems detect and neutralize malware, ransomware, and suspicious behavior automatically. Regular security patching and automated updates keep your network resilient against evolving threats, while expert oversight ensures vulnerabilities are addressed quickly and thoroughly, reducing your exposure to cyberattacks.

Comprehensive incident response coordination ensures your team is never alone during a cyber event. Nessit’s MDR services provide step-by-step guidance and direct support, from threat identification through full containment and recovery. This includes clear communication with your team, integration with regulatory partners for compliance, and post-incident reviews to strengthen your future defenses.

Ongoing risk assessment and IT maturity audits are an integral part of Nessit’s MDR services. Regular reviews identify new vulnerabilities, assess the effectiveness of your security controls, and provide actionable recommendations for improvement. Transparent reporting and documentation ensure your organization is always prepared for regulatory reviews and can demonstrate a strong security posture to stakeholders.

Employee cybersecurity training and phishing simulation are embedded within Nessit’s MDR offering. Empower your staff to recognize and avoid common threats with engaging awareness programs and real-world testing.
