Zero Trust: The Alternatives To Consider

October 8, 2024

What is Zero Trust and Why It’s Important

Zero Trust is a cybersecurity model that challenges the traditional perimeter-based security approach. In a zero-trust architecture, the assumption is that no user, device, or system should be trusted automatically—whether inside or outside the network. This model emphasizes continuous verification of users and devices, strict access controls, and least privilege access policies. In an era of increasing remote work, cloud services, and cyber threats, Zero Trust ensures that every access request is thoroughly validated before granting access to any resources.

The importance of Zero Trust lies in its ability to mitigate insider threats, prevent lateral movement within the network, and defend against sophisticated attacks. By ensuring all access is authenticated and authorized, companies can reduce the risk of breaches, even if some systems are compromised.

To dive deeper into the various aspects of Zero Trust, Andre Slonopas from The American Public University has written up a valuable piece for further reading.

Key Zero Trust Providers to Consider

Several leading companies offer Zero Trust Network Access (ZTNA) solutions. The main ones include:

Zscaler: A cloud-native ZTNA provider known for scalability and security at the enterprise level.
Netskope: A key player in securing cloud environments and offering granular access controls.
Cloudflare: A popular, cost-effective ZTNA solution, especially for businesses looking for robust performance and security combined with a global edge network.
Palo Alto Networks: Known for its advanced threat protection and integration across cloud, on-prem, and hybrid environments.
Cisco Zero Trust: Provides seamless identity and access management solutions that integrate with their larger networking and security ecosystem.

Zscaler, Netskope, and Cloudflare

When narrowing down your options, Zscaler, Netskope, and Cloudflare stand out as strong contenders. Each provider has its own unique strengths and target markets.

Zscaler

Zscaler is a highly scalable, cloud-native ZTNA provider that offers secure, seamless access to both on-premises and cloud applications. It’s an excellent choice for large enterprises with complex, distributed environments. Zscaler’s core strength lies in its ability to reduce the attack surface by hiding applications from public exposure and only allowing authenticated access. Additionally, it offers dynamic policy enforcement and real-time traffic inspection, making it a top choice for organizations needing robust security at scale.

Netskope

Netskope is another leading ZTNA provider, particularly strong in securing cloud applications and services. It is known for its advanced threat detection and data loss prevention (DLP) capabilities, which are essential for businesses heavily reliant on cloud-based solutions. Netskope offers granular access controls based on user identity, device posture, and app risk, ensuring that security policies adapt dynamically to changing conditions. Its strength in providing visibility into “shadow IT” (unsanctioned cloud apps) is also a key differentiator.

Cloudflare

Cloudflare, originally known for its content delivery network (CDN) services, has grown into a significant player in the ZTNA space with its Cloudflare One platform. Cloudflare’s solution is particularly well-suited for small and medium-sized businesses that need a cost-effective, scalable ZTNA option. Its Cloudflare Access product replaces traditional VPNs by providing identity-based secure access to applications and services, leveraging Cloudflare’s vast global edge network for performance optimization. While not as feature-rich as Zscaler or Netskope in some areas, Cloudflare stands out for its affordability, ease of use, and strong DDoS protection features.

Conclusion

Choosing the right Zero Trust provider depends on your organization’s specific needs. Zscaler excels in providing enterprise-level security for complex, distributed networks, while Netskope is ideal for organizations that require deep cloud visibility and granular controls. Cloudflare offers a more affordable option, perfect for businesses that prioritize ease of integration, performance, and scalability.

When evaluating Zero Trust Network Access solutions, it’s essential to benchmark providers based on security features, scalability, cost, and ease of integration into your existing infrastructure. Regularly revisiting and comparing vendors can help ensure you’re getting the best value, whether you’re sticking with your current provider or exploring alternatives.
