Managed security service providers monitor and manage cybersecurity measures, such as blocking viruses and spam, detecting intrusions, setting up firewalls, and managing virtual private networks (VPN). MSSPs are also in charge of things like system upgrades and alterations.

FREMONT, CA: MSSPs can be used to outsource all or a portion of an organization's IT security functions. These businesses provide a range of security-related services, including continuous security monitoring, vulnerability risk assessment, threat intelligence and assessment, intrusion management, video surveillance, and access control. Additionally, MSSPs can provide security recommendations and some level of continuous security and develop policies to assist a business in protecting its infrastructure.

MSSPs are a simple and efficient way to protect data and networks from intrusions while also reducing the process's complexity. For instance, hiring an in-house cybersecurity team can be more expensive than partnering with a managed security services provider. MSSPs can also assist businesses in reducing costs associated with equipment and software tools.

Due to increased security threats, large enterprises typically benefit from MSSP services. However, as security threats evolve, many small and medium-sized businesses (SMBs) can benefit from MSSPs. MSSP demand is increasing, with the global managed security services market expected to reach $46.4 billion in 2025.

Managed security service categories

Consultation on-site: MSSP consulting is when an MSSP comes in and conducts a comprehensive security assessment of a business's network, identifying potential and actual vulnerabilities. On-site MSSP consulting entails the MSSP identifying security holes and assisting the business in closing them.

Management of the client's network's perimeter: A perimeter is a conceptual line that divides an organization's internal assets from its public assets in the context of network security. If a single enterprise network is used for security, the perimeter is defined as the defenses that surround the network, preventing it from being attacked from the outside. A perimeter's purpose is to restrict access to sensitive data, typically limiting who and what can enter the network. Managed security services provider (MSSP) can provide security to a large enterprise; a critical component of the job is to ensure that the organization's network perimeter is secure and that all devices are adequately protected.

Resale of products: Resale of products is not a managed service but a revenue stream for MSSPs. A managed services provider (MSSP) resells its clients' software, hardware, and services. For instance, an MSSP may maintain a catalog of security devices, such as intrusion prevention systems and firewalls, from which clients can select from a range of specialized offerings. Additionally, the reseller may provide technical support for the devices, conduct security penetration tests, and conduct security audits. When large companies dominated the market, each with its security products, the MSSP model emerged. Customers would then receive a customized security solution comprised of products from multiple vendors through resellers.

Security monitoring on a managed basis: Typically, the first step in responding to a security incident report is managed security monitoring. It entails monitoring security events such as user logins and permission changes daily and investigating such system events across the network.
