Network security service providers protect IT infrastructure from unauthorized internal or external access.

The services take over that function from IT teams to enable internal IT resources to focus on more strategic business priorities. Security services can also fill in gaps when internal staff aren’t on duty, like nights and weekends – when cyber attacks still happen.

Network security providers are in high demand, whether through vendors offering networking software and hardware or as networking as a service provided by managed service providers (MSPs).

Dell’Oro Group’s latest Network Security five-year forecast report found that demand for software-as-a-service (SaaS) and virtual-based network security is expected to become 51% of the $33 billion total network security market by 2026.

A ‘Seismic Shift’ in Networking

Since the arrival of the first network security appliances in the 1980s, the dominant approach for network security solutions companies has been to sell an assortment of purpose-built boxes. But a seismic shift is taking place.

“Cloud-centric security will continue to grow faster than the overall market,” said Mauricio Sanchez, an analyst at Dell’Oro. “Between enterprises embracing cloud applications and hybrid work as the new normal, we see them preferring SaaS- and virtual-based network security solutions that serve these use cases better.

“This is not to say that we see hardware security appliances disappearing, but they no longer represent the vanguard of network security they once were.”

SaaS- and virtual-based web application firewalls (WAFs), for example, are expected to grow 25% each year from 2021 to 2026. Other network security services with a similar growth trajectory are secure web gateways (SWGs) and other networking elements that are part of the secure access service edge (SASE) architecture (see our MSP Guide to SASE).

At the other end of the scale, the once ubiquitous physical firewall appliance, which accounted for more than 75% of total hardware-based network security spending in 2020, is expected to grow at a solid but unspectacular 7% a year for the next half decade.

What is a Network Security Service?

Network security services protect organizational infrastructure and any connected servers or devices from undesirable access, mishandling, or cyberattack. Instead of providing a firewall or appliance for internal IT resources to run the equipment, external service providers take care of support, updating, and running network security operations.

There is a wealth of network security services available. These include WAFs, SWGs, SD-WANs, managed firewalls, ransomware prevention, managed detection and response (MDR), intrusion response (IR), and more.

Why Use a Network Security Service?

Organizations face a wide range of advanced and automated attacks that look to evade traditional security technologies and approaches. To successfully counter and protect against these threats, security solutions and teams need to detect and respond to attacks in near real time.

Therefore, purchasing security as a service from a trusted vendor is a good way to supply the agility and resources that would otherwise overwhelm resource-constrained security teams. These vendors often have the resources to heavily invest in threat research and cross-industry threat intelligence sharing as well as possessing a talent pool that would be hard for other organizations to acquire. In all likelihood, this is the best way to enhance organizational resiliency against advanced attacks and prevent zero-day and ransomware attacks.

Cloud-delivered security services provide the policy consistency needed across an organization with distributed infrastructure from data centers, campuses, branches, home offices, and multi-cloud deployments. When security is natively integrated with networking, it allows organizations to dynamically and securely adapt to things like shifting connectivity needs, remote workers, or applications that may need to move between hybrid IT architectures.

“Lack of talent, time, or training often drive companies to deploy network security services,” said Tommy Smith, vice president of Avertium. “In many instances, it can be more cost effective to have the MSSP bear the cost of purchasing, maintaining, and upgrading the technology than it would be done by the enterprise.”

Core Features of a Network Security Service

According to Fortinet, the core minimum features buyers should look for in a network security service solution provider are:

  • Strong security research and fast implementation of innovation to stay ahead of threats, with rapid consumption of advanced security innovations across web, content, and device attack vectors
  • Security that is natively integrated to help coordinate detection, analysis, and protection across the organization
  • The ability to cover networks, endpoints, and clouds with context-aware policies to provide consistent security for hybrid deployments
  • A user-based, as-a-service licensing model that allows users to easily predict costs, scale the business, and simplify the purchasing process across hybrid IT deployments
