MPLS (Multiprotocol Label Switching) has long been the bedrock of enterprise networking, providing a reliable and efficient way to transmit data across networks. Its widespread adoption is no surprise, given its ability to prioritize traffic, reduce latency, and offer robust security features.
However, as the digital landscape evolves at breakneck speed, the once-revered MPLS is showing signs of strain, struggling to keep pace with the demands of modern networking.
The Rise of MPLS in Enterprises
Enterprises worldwide have embraced MPLS for its reliability and performance. MPLS creates a private, secure network that ensures data reaches its destination quickly and efficiently. By using labels to direct traffic rather than looking at IP addresses, MPLS can speed up packet forwarding and reduce the need for complex routing tables, leading to faster data transmission and lower latency.
Moreover, MPLS allows for Quality of Service (QoS) implementation, enabling enterprises to prioritize critical data traffic over less important traffic. This feature is crucial for applications like VoIP, video conferencing, and real-time data analytics, where latency and packet loss can severely impact performance.
Challenges and Risks of Legacy MPLS Networks
Despite its advantages, legacy MPLS networks are facing significant challenges in today’s digital landscape. One of the primary concerns is security. MPLS was designed in an era when security threats were less sophisticated and less prevalent. Modern cyber threats, such as ransomware, DDoS attacks, and data breaches, pose a significant risk to MPLS networks that may not have been designed with such threats in mind.
Another challenge is the lack of flexibility and scalability in legacy MPLS networks. As enterprises undergo digital transformation, they need networks that can adapt to new technologies and rapidly changing business requirements. MPLS networks, with their static configurations and limited agility, can hinder rather than facilitate digital innovation.
Moreover, maintaining MPLS networks can be expensive, particularly for enterprises with a global footprint. The costs of leasing lines from service providers, managing hardware, and implementing security measures can add up quickly, especially when compared to newer, more cost-effective networking technologies.
The Hidden Costs of Legacy MPLS
Multiprotocol Label Switching (MPLS) has long been a go-to solution for enterprises seeking reliable and secure networking. However, beneath its veneer of reliability lies a network infrastructure that can incur significant hidden costs, particularly as enterprises strive to meet modern data demands and keep pace with digital transformation.
Operational Costs and Maintenance
One of the most significant hidden costs of maintaining legacy MPLS infrastructure is the high operational and maintenance expenses. MPLS networks require specialized hardware and software, which can be expensive to purchase and maintain. Additionally, MPLS networks often require dedicated IT personnel to manage and troubleshoot issues, adding to the overall operational costs.
Furthermore, MPLS networks are not easily scalable, requiring additional hardware and configuration changes to accommodate growth or changes in network traffic patterns. These scalability limitations can result in increased operational costs as enterprises struggle to keep up with evolving network requirements.
Bandwidth Limitations and Costly Upgrades
Another hidden cost of legacy MPLS is the bandwidth limitations inherent in the technology. MPLS networks were designed for a time when data traffic was more predictable and less bandwidth-intensive. However, as enterprises increasingly rely on bandwidth-hungry applications such as video conferencing, cloud computing, and big data analytics, MPLS bandwidth limitations become more pronounced.
To address these limitations, enterprises often find themselves faced with the prospect of costly upgrades to their MPLS infrastructure. Upgrading MPLS to support higher bandwidths can involve replacing hardware, renegotiating service contracts with providers, and incurring additional setup and configuration costs. These costs can quickly add up, making MPLS upgrades a significant financial burden for enterprises.
Security Risks and Vulnerabilities in MPLS Networks
Multiprotocol Label Switching (MPLS) has long been praised for its efficiency and performance in enterprise networking. However, beneath its apparent strengths lies a network infrastructure that poses several security risks and vulnerabilities, particularly in the face of evolving cyber threats.
Lack of Encryption and Vulnerability to Cyberattacks
One of the primary security vulnerabilities of MPLS is its lack of inherent encryption. MPLS was designed to provide fast and efficient routing of data packets, prioritizing speed and performance over security. This lack of encryption makes MPLS networks susceptible to cyberattacks such as man-in-the-middle attacks, where an attacker intercepts and potentially alters the communication between two parties.
Without encryption, sensitive data transmitted over MPLS networks is exposed to potential eavesdropping and tampering, putting enterprises at risk of data breaches and unauthorized access.
Challenges of Securing MPLS Networks
Securing MPLS networks against emerging threats such as ransomware and advanced persistent threats (APTs) poses significant challenges for enterprises. Ransomware attacks, in which attackers encrypt data and demand payment for its release, can cripple an organization’s operations and reputation.
APTs, on the other hand, are sophisticated and stealthy attacks that target specific organizations over an extended period. These attacks often exploit vulnerabilities in network infrastructure, including MPLS, to gain unauthorized access to sensitive information.
Securing MPLS networks against these threats requires a multi-layered approach that includes encryption, intrusion detection and prevention systems (IDPS), and regular security audits and updates. However, implementing these security measures can be complex and costly, particularly for enterprises with large and geographically dispersed networks.
Enhancing MPLS Security
To enhance the security of MPLS networks, enterprises can implement several key measures:
- Encryption: Implementing encryption technologies such as IPsec (Internet Protocol Security) can help protect data transmitted over MPLS networks from eavesdropping and tampering.
- Access Control: Implementing strict access control policies and using technologies such as VLANs (Virtual Local Area Networks) can help prevent unauthorized access to MPLS networks.
- Intrusion Detection and Prevention: Deploying IDPS can help detect and prevent cyberattacks on MPLS networks, including ransomware and APTs.
- Regular Security Audits: Conducting regular security audits and updates can help identify and mitigate vulnerabilities in MPLS networks.
Operational Challenges and Limitations of MPLS Networks
Multiprotocol Label Switching (MPLS) has long been a staple in enterprise networking, providing a reliable and efficient way to transmit data. However, as the digital landscape evolves, MPLS networks are facing operational challenges and limitations, particularly in the context of remote workforces, cloud adoption, and the demands of modern applications and digital initiatives.
Managing and Scaling MPLS Networks
One of the primary operational challenges of MPLS networks is managing and scaling them to meet the needs of modern enterprises. MPLS networks are complex and require specialized knowledge to configure and maintain properly. As enterprises grow and their networking requirements evolve, managing and scaling MPLS networks can become increasingly challenging and resource-intensive.
Moreover, the rise of remote workforces has added another layer of complexity to MPLS network management. Remote workers require secure and reliable access to corporate networks, which can strain MPLS resources and require additional configuration and security measures.
Limitations in Supporting Modern Applications and Digital Initiatives
MPLS networks also face limitations in supporting modern applications and digital initiatives. MPLS was designed for a time when data traffic was more predictable and less bandwidth-intensive. However, as enterprises adopt cloud computing, IoT deployments, and real-time communications, MPLS bandwidth limitations become more pronounced.
Cloud computing, in particular, poses challenges for MPLS networks. MPLS was not designed to handle the high data volumes and dynamic traffic patterns associated with cloud computing. As a result, enterprises may experience latency and performance issues when accessing cloud-based applications over MPLS networks.
Similarly, IoT deployments and real-time communications require low latency and high bandwidth, which can be challenging to achieve with MPLS. IoT devices generate large amounts of data that need to be transmitted quickly and efficiently, while real-time communications require seamless connectivity and minimal latency.
Embracing Change: The Current State
To address these challenges, many enterprises today are transitioning from MPLS to SD-WAN (Software-Defined Wide Area Network). SD-WAN offers a more flexible and cost-effective alternative to MPLS, allowing enterprises to leverage multiple connection types, including broadband, MPLS, and LTE, to create a hybrid network that meets their specific needs.
However, while both SD-WAN and SASE offer benefits in terms of network performance and security, they are designed to address different aspects of networking. SD-WAN focuses on improving WAN performance and reliability, while SASE provides a comprehensive security framework that integrates networking and security services.
Specifically…
SD-WAN is a technology that simplifies the management and operation of a WAN by separating the networking hardware from its control mechanism. It uses software to dynamically direct traffic across the WAN based on the current conditions of the network, such as traffic load, latency, and link availability.
Whereas…
SASE is a comprehensive security framework that integrates networking and security services into a single, cloud-native platform. It combines SD-WAN capabilities with security functions such as secure web gateways, firewall as a service, and zero-trust network access.
The SASE Solution: A More Secure and Agile Alternative
Today, enterprises are constantly seeking solutions that can provide both robust security and agile networking capabilities.
One such solution that has been gaining traction in recent years is Secure Access Service Edge (SASE). SASE is a comprehensive cybersecurity framework that integrates networking and security services into a single, cloud-native platform, offering a more secure and agile alternative to traditional networking technologies such as MPLS.
Introducing SASE: A Comprehensive Cybersecurity Framework
SASE, pronounced “sassy,” was coined by Gartner in 2019 to describe a new approach to network security that combines wide-area networking (WAN) capabilities with security functions such as secure web gateways, firewall as a service, and zero trust network access. SASE is designed to provide secure access to applications and data from any location or device, making it ideal for today’s distributed and remote workforce.
One of the key advantages of SASE is its ability to provide consistent security and networking policies across the entire enterprise, regardless of the user’s location or the device they are using. This consistency is achieved through the use of cloud-native technologies and software-defined networking (SDN), which allow for the rapid deployment and scaling of security and networking services.
Addressing the Limitations of MPLS
While MPLS has been a reliable networking technology for many years, it has several limitations that make it less suitable for today’s digital landscape. MPLS is expensive to deploy and maintain, particularly for enterprises with large and geographically dispersed networks. Additionally, MPLS is not well-suited for cloud environments, as it lacks the flexibility and scalability required to support cloud-based applications and services.
SASE addresses these limitations by providing a cloud-native, software-defined approach to networking and security. With SASE, enterprises can leverage the scalability and flexibility of the cloud to deploy and manage networking and security services more efficiently. SASE also provides built-in security features such as encryption, micro-segmentation, and identity and access management, making it more secure than traditional networking technologies like MPLS.
The Benefits of SASE
One of the key benefits of SASE is its ability to reduce complexity and improve operational efficiency. By integrating networking and security services into a single platform, SASE eliminates the need for multiple point solutions, reducing the complexity of managing and securing the network.
SASE also provides greater flexibility and scalability than traditional networking technologies. With SASE, enterprises can quickly and easily scale their networking and security services to meet changing business requirements, without the need for costly hardware upgrades or reconfigurations.
SASE offers a more secure and agile alternative to traditional networking technologies like MPLS.

As more enterprises embrace remote work and cloud computing, SASE will become an increasingly important component of their cybersecurity and networking strategies.
Benefits of SASE Over MPLS
As enterprises continue to embrace digital transformation, the need for secure, agile, and cost-effective networking solutions has never been greater. Secure Access Service Edge (SASE) has emerged as a powerful alternative to traditional networking technologies like Multiprotocol Label Switching (MPLS), offering a range of benefits that address the shortcomings of MPLS and meet the demands of modern enterprises.
Cost Savings
One of the key benefits of adopting SASE over MPLS is cost savings. MPLS requires expensive hardware such as routers and switches, as well as dedicated lines from service providers. In contrast, SASE is cloud-native and software-defined, eliminating the need for costly hardware and reducing operational expenses. With SASE, enterprises can scale their networking and security services more efficiently, avoiding the need for expensive hardware upgrades and reducing overall costs.
SASE also simplifies network management, further reducing costs. With MPLS, enterprises often have to manage multiple point solutions for networking and security, leading to complexity and increased management overhead. SASE integrates networking and security services into a single platform, streamlining management and reducing the need for multiple solutions.
Enhanced Security
Security is another area where SASE shines compared to MPLS. MPLS networks are inherently insecure, lacking built-in encryption and relying on trust-based models for access control. SASE, on the other hand, incorporates security features such as encryption, zero-trust principles, and threat intelligence capabilities.
Encryption is crucial for protecting data in transit, especially as data breaches and cyberattacks become more common. SASE provides built-in encryption for data transmitted over the network, ensuring that sensitive information remains secure.
Zero-trust principles are another key aspect of SASE’s security model. Unlike MPLS, which assumes that everything inside the network is trustworthy, SASE operates on the principle of “never trust, always verify.” This means that even within the network, users and devices are continually authenticated and authorized, reducing the risk of insider threats and unauthorized access.
Threat intelligence capabilities are also a crucial component of SASE’s security features. SASE platforms are equipped with threat intelligence feeds that continuously monitor the network for potential threats and vulnerabilities. This proactive approach to security helps enterprises stay ahead of cyber threats and protect their data more effectively.
The benefits of adopting SASE over MPLS are clear: SASE offers cost savings through reduced hardware costs, simplified management, and improved scalability.
It also enhances security through built-in encryption, zero-trust principles, and threat intelligence capabilities. As enterprises continue to navigate the complexities of digital transformation, SASE provides a secure, agile, and cost-effective networking solution that meets their evolving needs.
