This comprehensive guide delves into the definition of managed network security and its pros and cons to help you make an informed decision for your organization.

What Is Managed Network Security?

Managed network security refers to the practice of outsourcing an organization's network security management and monitoring to a third-party service provider, often called a Managed Security Service Provider (MSSP). These providers specialize in delivering end-to-end network security services encompassing threat detection, prevention, and remediation. As a result, organizations can focus on their core business operations while relying on MSSPs to maintain a secure and protected network.

  4. Anti-malware and anti-virus protection: Deploying, updating, and monitoring anti-malware and anti-virus software to protect against various types of malware, including viruses, ransomware, and other threats.
  5. Security Information and Event Management (SIEM): Collecting and analyzing security-related data from various sources to identify patterns, trends, and potential threats, facilitating real-time responses and informed decision-making. Read more about SIEM here.
  6. Vulnerability management: Regularly scanning the network for security vulnerabilities and weaknesses, and recommending or implementing patches and updates to minimize risks.
  7. Patch management: Ensuring that all software, hardware, and network components are up-to-date with the latest security patches to prevent exploitation by cybercriminals.
  8. Data loss prevention (DLP): Implementing tools and policies to detect and prevent unauthorized access, transmission, or storage of sensitive data.
  9. Distributed Denial of Service (DDoS) mitigation: Monitoring for and mitigating DDoS attacks by filtering malicious traffic and maintaining network availability during an attack.
  10. Security awareness training: Providing training and resources to educate employees about security best practices, common threats, and their role in maintaining a secure network environment.

  2. Protection outside of regular business hours: MSSPs provide 24/7 monitoring, ensuring that organizations' networks remain protected even when the in-house IT team is off-duty.

Compliance

  1. Adherence to data security regulations: Many industries have strict data security regulations such as PCI-DSS, HIPAA or SOC-2, and MSSPs are often well-versed in these requirements.
  2. Assistance with maintaining compliance: MSSPs can help ensure that an organization's network security measures are compliant with the relevant standards, reducing the risk of regulatory fines or penalties.

Cons of Managed Network Security

Limited control

  1. Challenges of relinquishing control over cybersecurity measures: Outsourcing network security may require organizations to give up some control over their cybersecurity measures, which can be a difficult adjustment for some businesses.
  2. Adjustments for businesses: It's important for organizations to find a balance between maintaining control and trusting the MSSP to effectively manage their network security.

Dependency on third-party providers

  1. Reliability and performance of MSSPs: When outsourcing network security, an organization's protection depends on the MSSP's reliability and performance. Careful evaluation of potential providers is essential to minimize risks.
