The internet as a commercial and social enterprise began taking root and growing in the mid-1990s. Back then, all the components for data pipelines – traffic routers, cables, access points, switches, network cards, and storage nodes – were hardwired inside data centers.

Application service providers (ASPs) in the late 1990s were the early providers of new internet-borne software apps made available by subscription. But those early software-as-a-service (SaaS) providers were constantly going down due to hackers, hitches in the technology, and high traffic volumes. Security was porous and payloads couldn't be delivered reliably. Like anything else, the category had growing pains, and it needed continuous innovation to improve itself.

In the late 2000s came SDN, which liberated networking from a lot of its hardware and became the key tool for new network managed service providers (MSPs) so they could host enterprise networking on the web.

Networking has indeed improved, and business over the web was able to grow tremendously over a 20-year period. However, in 2024, an increasing number of enterprises are realizing that their legacy networking systems are decades old and need replacement; they're planning to move all their networking processes to the cloud as the next step. Two of the choices they have are the old-school MSPs (direct descendants of the ASPs) and next-generation network-as-a-service (NaaS) specialists.

NaaS versus MSP boils down to one key fact: NaaS manages most, if not all, aspects of the network; MSPs do not. Both NaaS and MSPs offer businesses ways to outsource their network management, but they differ significantly in their approach and scope.

Here's a breakdown of their key differences and similarities:

NaaS

• Focus: Provides networking services such as bandwidth, security, and network management on a subscription basis. Think of it as cloud computing for a network infrastructure.
• Delivery: Delivered as an all-inclusive cloud-managed service with bundled purpose-built technologies like SD-WAN, zero-trust network access (ZTNA), and artificial intelligence (AI) operations (AI Operations (AIOps)) built to work together seamlessly.
• Scalability: You can adjust network resources (bandwidth, security features, coverage, etc.) as needed.
• Efficiency: Network lifecycle management is completely covered, with hands-off proactive troubleshooting, remediation, and performance optimizations.
• Cost structure: Predictable, subscription-based pricing, usually considered an operating expense.

• Focus: Offers a menu of IT services, including network management, cybersecurity, data backup, recovery, and help-desk support.
• Delivery: Can be delivered on-site, remotely, or a hybrid of both.
• Scalability: Can be less scalable than NaaS because scaling often requires manual intervention or contract renegotiation.
• Control: The flipside of efficiency with NaaS is that MSPs need customer approval for most management, hardware line cards/provisioning, maintenance, and upgrade actions.
• Cost: Can vary depending on the services provided, often a mix of project-based and recurring fees.

Advantages of deploying NaaS Let's explore the advantages NaaS offers.

Scalability and adaptability for the enterprise: NaaS gives businesses scalability and adaptability. With on-demand resources, companies can scale bandwidth and network capabilities in response to evolving business needs, such as seasonal peaks, new product launches, or rapid expansion. This agility extends to rapid deployment of new network connections and support for remote workforces and branch offices, ensuring secure and optimized connectivity – regardless of location.

Financial efficiency and predictability: NaaS presents an attractive financial proposition for businesses. By eliminating the need for substantial upfront investments in networking hardware, NaaS significantly reduces capex. Instead of large, unpredictable hardware purchases, businesses transition to a predictable operational expenditure model with manageable subscription fees, streamlining budgeting and forecasting processes. Furthermore, by reducing reliance on in-house networking expertise, NaaS lowers ongoing IT costs associated with staffing and maintenance.

Performance and security: NaaS providers typically leverage cutting-edge network infrastructure and optimization technologies, resulting in enhanced network performance. NaaS solutions also come equipped with advanced security features, including firewalls, intrusion detection systems, and data encryption, providing strong defense against cybersecurity threats. By offloading network management to experts, NaaS frees internal IT teams to focus on strategic initiatives.

Access to leading-edge expertise and innovation: Partnering with a NaaS provider grants businesses access to specialized knowledge in network design, implementation, and management. This expertise ensures optimal network configuration and performance. Additionally, NaaS allows companies to stay at the forefront of networking technology without significant investment, benefiting from the provider's continuous upgrades and advancements.

Navigating potential challenges: While NaaS offers compelling advantages, it's essential to acknowledge potential considerations. Vendor lock-in can pose a challenge, so careful evaluation of contract terms and provider flexibility is crucial. Compatibility with legacy systems should be assessed to ensure seamless integration with existing infrastructure. Furthermore, businesses must diligently evaluate the security practices and data privacy policies of potential NaaS providers to ensure alignment with their own security standards.

In summary, NaaS presents an opportunity for businesses to transform their network infrastructures into a source of competitive advantage. By carefully considering the potential challenges and selecting a reputable NaaS provider, enterprises can unlock new levels of operational flexibility and focus on driving core business objectives.

Strategic outsourcing: deploying MSPs for enterprise networking Let's examine the benefits and crucial considerations of this approach.

Cost optimization and predictable budgeting: Outsourcing network management to an MSP offers significant cost advantages. By eliminating the need to hire, train, and retain specialized in-house networking personnel, businesses can significantly reduce operational expenses. MSPs typically offer predictable monthly or annual fees, facilitating accurate budgeting and financial forecasting. MSPs often eliminate the need for capital-intensive investments in networking hardware.

Access to expertise and support: MSPs bring a wealth of specialized knowledge and experience to the table. Businesses gain access to certified network engineers and technicians who possess in-depth expertise in network design, implementation, and management. This translates into proactive 24/7 monitoring and management of network infrastructure, ensuring optimal performance and rapid issue resolution. With an MSP at the helm, businesses can expect swift response times and efficient troubleshooting of network problems, minimizing downtime and maximizing productivity.

Strengthened security posture and compliance: Cybersecurity is a paramount concern for modern enterprises. MSPs implement strong security protocols and cutting-edge IT to safeguard a network from evolving threats. Their expertise extends to navigating complex industry specific security and compliance requirements, ensuring a business remains protected and compliant. Through regular security assessments, vulnerability management, and proactive threat mitigation, MSPs provide a full-fledged security shield for network infrastructure.

Enhanced efficiency and scalability for business growth: By entrusting network management to an MSP, internal IT teams can redirect their focus toward strategic projects that drive innovation and business growth. MSPs offer scalable solutions that readily adapt to evolving business needs. Through optimized network configurations and performance tuning, MSPs ensure a network operates at peak efficiency, supporting seamless business operations and expansion.

Navigating potential challenges with due diligence: While partnering with an MSP offers numerous advantages, it's essential to acknowledge and address potential considerations. Entrusting network management to an external provider inevitably involves some degree of relinquishing direct control. It's crucial to select an MSP that offers transparency, clear communication channels, and robust service level agreements (SLAs) to ensure alignment with business objectives. Furthermore, businesses should diligently evaluate the MSP's security practices, data privacy policies, and contract terms to mitigate potential risks and ensure a successful partnership.

In summary, engaging an MSP for enterprise networking can be a strategic move that unlocks significant benefits in terms of cost savings, enhanced expertise, improved security, and increased efficiency. However, it's crucial to conduct thorough due diligence, carefully assess potential challenges, and select an MSP whose capabilities and values align with specific business needs and security standards.
