Small to medium-size businesses stare down a distinct set of challenges when it comes to cybersecurity. With more companies shifting toward cloud-based solutions and remote work, traditional security just doesn’t cut it anymore. This is where architectural models such as Secure Access Service Edge (SASE — pronounced “sassy”) and Zero Trust enter the frame.

But what do these terms mean, and why are they essential for your business?

Let’s dive in, and we’ll explore how QuantaSi can guide your business in adopting these strategies.

What’s the Difference?

While SASE and Zero Trust are distinct concepts, they’re complementary to each other. Zero Trust can be seen as a core component within the broader SASE framework. SASE architectures often incorporate Zero Trust principles to ensure secure, context-aware access to resources, aligning with the Zero Trust mandate of “never trust, always verify.” Together, they create a potent approach for securing modern, distributed networks and resources by combining advanced networking capabilities with strict access controls based on continuous trust assessment.

Understanding SASE

Traditional networking is like having all your valuables in one vault — accessing them means going through a single, central location. This setup struggles to keep up with modern, cloud-based services and the decentralized nature of today’s work environments.

SASE, on the other hand, spreads security controls across the cloud. It simplifies the network by merging multiple security functions under one roof, which enhances security and makes management a breeze. QuantaSi’s SASE model adapts seamlessly to the needs of clients using cloud services, allowing for secure, efficient access to applications and data from anywhere.

The Components of SASE

Transitioning to a SASE architecture can be a step-by-step process, allowing businesses to prioritize their immediate needs before fully integrating all aspects of networking and security into a single platform.

Key technologies under the SASE umbrella include Zero Trust, Secure Web Gateways (technology that filters internet traffic and enforces regulatory policy compliance), Cloud Access Security Brokers (monitoring the activity between cloud users and applications) and Software-Defined Wide Area Networking (ensures critical applications are prioritized and receive necessary bandwidth), among others. These components work together to ensure secure and reliable access to network resources, regardless of where users or applications are located.

Why Zero Trust Matters for SMBs

Like “Stone Cold” Steve Austin often barked from the wrestling ring: “Don’t trust anybody.”  Zero Trust is a cybersecurity principle of verifying all users. Differing from traditional security approaches, Zero Trust assumes threats can exist both outside and inside the network. Therefore, it requires verifying the identity and security compliance of every user and device trying to access resources in the network, regardless of their location.

Key aspects of the Zero Trust model include:

Least Privilege Access: Users and devices are given the minimum level of access needed to perform their duties. This limits the potential damage from breaches or insider threats.

Microsegmentation: The network is divided into small, secure zones to control sensitive information and applications separately. This approach limits an attacker’s ability to move laterally across the network.

Multi-factor Authentication (MFA): MFA requires users to provide two or more verifiable factors to gain access to resources, adding an additional layer of security beyond a password.

Continuous Verification: Trust is never assumed to be constant. The security posture of users and devices is continuously, and access is adjusted based on risk.

Encrypt Data: Data is encrypted both in transit and at rest to protect it from unauthorized access and interception.

Explicit Verification: Every access request must be authenticated, authorized and encrypted before granting access, regardless of the user’s location or the network’s entry point.

Zero Trust is particularly effective when organizations use cloud services, and employees access systems remotely from various devices and locations. By implementing Zero Trust with an MSP such QuantaSi, organizations can significantly enhance their security posture by assuming their network is always at risk and proactively verifying every access request.
