Security teams are stretched thin. Between VPN clients that frustrate remote workers, firewall rules that take weeks to update, and separate consoles for web filtering, endpoint protection and network segmentation, there’s barely time left to focus on actual threats. Each tool solves one problem while creating three others.
This patchwork approach does more harm than good. The classic perimeter has disappeared. Employees work from anywhere. Applications run everywhere. The attack surface keeps expanding while your team’s capacity stays flat.
Secure Access Service Edge (SASE) takes a different approach. It consolidates networking and security into a single, cloud-managed platform. Instead of bolting security onto your network as an afterthought, you build it in from the start. Less complexity, more visibility, genuine control over who accesses what.
The problem with traditional security
Hybrid work and SaaS adoption have permanently changed how businesses operate. Employees, data and applications are no longer confined to a central office. This creates flexibility, but also a sprawling attack surface that traditional tools weren’t built to protect.
VPNs and firewalls fall short. These tools were designed to protect a clearly defined perimeter. When employees access corporate resources from home, coffee shops and airports, that perimeter no longer exists. VPNs are slow and cumbersome, providing overly broad access once a user connects. Firewalls become a bottleneck and a management nightmare when trying to secure a decentralised workforce.
Network segmentation offers false security. Many organisations rely on segmentation to contain threats by dividing the network into zones to limit an attacker’s movement. In practice, once an attacker gains a foothold (perhaps through a successful phishing email), they can often still move laterally across insecure segments to reach critical systems.
Unmanaged devices create blind spots. BYOD policies, IoT sensors and connected industrial machinery introduce countless endpoints that traditional security can’t see or manage. These agentless devices become easy entry points for attackers.
IT teams end up struggling with a complicated web of disparate tools. More complexity means more configuration errors, slower troubleshooting and significant security gaps.
How SASE changes the game
SASE isn’t another security product to add to your stack. It consolidates multiple functions into a single, cloud-delivered service that protects all your users, devices and applications regardless of location.
Zero Trust Network Access (ZTNA) operates on a “never trust, always verify” model. Instead of granting broad network access like a VPN, ZTNA provides secure, granular access to specific applications based on user identity and device posture. If a breach occurs, lateral movement becomes much harder.
Software-Defined WAN (SD-WAN) optimises network performance by intelligently routing traffic over the most efficient path. It provides secure, high-speed connectivity between branch offices and data centres, which makes it well suited for hybrid environments.
Cloud-delivered security services include Secure Web Gateway (SWG) to protect against web-based threats, Firewall-as-a-Service (FWaaS) for consistent policy enforcement, and device posture checks that verify endpoints before granting access.
These components work together under one roof. Instead of juggling multiple consoles and complex rule sets, you manage everything from a single platform. You see what’s happening across your entire network.
The business benefits
SASE delivers advantages that go beyond security improvements.
Cost savings through consolidation
Consolidating multiple security products into one platform can reduce security costs significantly. One platform means fewer vendors to manage, fewer licenses to renew and less hardware to maintain. A unified SASE platform can cut security costs by up to 60% by replacing expensive firewalls and VPNs with a single, cloud-based solution. IT teams spend less time on tedious configuration and more time on work that actually matters.
Secure remote access that works
SASE was built for the hybrid workforce. It provides secure remote access based on user identity, not network location. Employees connect securely and efficiently from any device, anywhere, without the performance lag of traditional VPNs. Productivity goes up while sensitive data remains protected.
Simplified compliance and reporting
Meeting regulatory requirements is a growing challenge. NIS2 and the Cyber Resilience Act place strict security obligations on organisations. A SASE platform provides the centralised visibility, control and logging needed to demonstrate compliance. With detailed reporting and identity-based access controls, you can show auditors that robust security measures are in place.
Scalability for MSPs and partners
Managed service providers need repeatable deployment processes across multiple clients. A multi-tenant SASE platform supports operations with consistent policies, transparent margins and manageable support overhead. Partners can serve all their customers from one console while delivering a complete security offering.
How to implement SASE
Transitioning to SASE requires planning, but the process doesn’t have to be overwhelming.
Assess your current infrastructure. Evaluate your existing network and security setup. Identify gaps, bottlenecks and complexity. Understanding your current state helps define what you need from a SASE solution.
Define your security requirements. What are your biggest concerns? What compliance standards must you meet? Outline specific needs, from remote access policies to threat protection capabilities.
Choose the right provider. Not all SASE solutions are equal. Look for a truly integrated platform, not just bundled separate products. Consider ease of implementation, management simplicity and pricing transparency. For European businesses, choosing a European provider offers advantages in GDPR compliance and local support.
Consider partnering with an MSP. For mid-sized businesses, leveraging a Managed Service Provider is often the most effective way to implement and manage SASE. An experienced MSP can help design, deploy and maintain your architecture without overburdening your internal team.
Start with quick wins. Begin with one business process or user group. Roll out ZTNA for a few applications, enable baseline web filtering and measure results before expanding. This phased approach delivers value quickly while managing risk.
Ready to simplify your security?
The way we work has changed permanently, and security must change with it. Continuing to rely on complex, outdated tools is no longer viable. SASE provides a clear path forward.
Consolidating security and networking into a single, cloud-managed platform reduces complexity, lowers costs and gives you the control you need in a distributed world.

Frequently Asked Questions
What is SASE?
SASE (Secure Access Service Edge) is a cloud-native security framework that combines networking and security services into a single, unified platform. It provides secure access for users from anywhere while simplifying management for IT teams.
How does SASE differ from a traditional firewall or VPN?
Traditional firewalls and VPNs were designed to protect a network perimeter. SASE is designed for a borderless world where users, devices and applications are everywhere. It uses a Zero Trust model to grant granular access based on identity, rather than providing broad network access like a VPN.
Is SASE suitable for small and medium-sized businesses?
Yes. While early SASE solutions were complex and targeted at large enterprises, providers like Jimber have made SASE accessible and affordable for mid-sized organisations. The simplicity and cost savings make it a strong business case for companies of all sizes.
What is Zero Trust Network Access (ZTNA)?
ZTNA is a core component of SASE. It assumes no user or device is trustworthy by default. Access to applications and resources is granted on a per-session basis only after the user’s identity and device posture have been verified.
How can SASE help with NIS2 compliance?
SASE provides centralised visibility, logging and control over network access, which are all needed for meeting NIS2 requirements. Identity-based access and detailed reporting make it easier to demonstrate robust security measures to auditors and regulators.
What about devices that cannot run agents?
NIAC hardware provides inline isolation for printers, IoT sensors and industrial equipment. This approach allows only defined communication flows while maintaining Zero Trust security controls, closing the blind spots that traditional tools leave open.
