What is SASE in Practical Terms?
Secure Access Service Edge, or SASE, is a modern approach to cybersecurity that unifies networking and security services into a single, cloud-managed platform. It connects users, devices, sites, and applications through a consistent policy framework that authorizes, inspects, and encrypts every connection. The primary goal is to achieve consistent security control with less operational complexity, providing a direct path to a Zero Trust security model for your entire organization.
As the SASE category matures, industry analysis helps leaders make informed decisions. Prominent research firms now offer detailed evaluations, comparing different vendor approaches and highlighting key trends in the convergence of network and security technologies. This helps CTOs and IT managers navigate the landscape effectively.
Why Unified SASE Matters for European Compliance
In 2025, European regulations are significantly raising the standards for cybersecurity control, monitoring, and reporting. A unified SASE platform is a powerful tool for meeting these new requirements efficiently.
- NIS2 Directive: With the transposition deadline of October 17, 2024, now passed, organizations classified as essential and important entities must demonstrate stronger risk management and incident reporting capabilities. NIS2 compliance is a key driver for security investment.
- DORA (Digital Operational Resilience Act): Applicable from January 17, 2025, DORA imposes uniform requirements on financial entities and their critical ICT providers. It covers ICT risk management, resilience testing, incident reporting, and third-party risk oversight.
- Cyber Resilience Act (CRA): The CRA introduces security obligations for products with digital elements. Its requirements will be phased in over the coming years, impacting how technology is developed and maintained.
A unified SASE platform helps you normalize security controls across all users and sites, whether remote or in-office. It centralizes logging and makes generating audit evidence a repeatable process. This not only improves your day-to-day resilience but also accelerates the time-to-value for your compliance programs.
Unified SASE vs. A Toolkit of Point Solutions
Many organizations still rely on a collection of separate security tools from different vendors, such as firewalls, VPNs, web filters, and SD-WAN solutions. This fragmented approach often leads to policy inconsistencies, duplicated logging efforts, and a disjointed user experience.
The Problem with Traditional Firewalls and VPNs
- Increased Risk: Broad network access granted by VPNs inflates the risk of lateral movement if an attacker gains entry.
- Poor Performance: Routing traffic through centralized data centers (hairpinning) adds latency for hybrid and remote workers.
- Complexity: Managing sprawling rule sets across multiple local firewalls is difficult to audit, version, and maintain.
The Advantages of Unified SASE
- Granular Control: Identity-based access maps specific users to the exact applications and services they need, implementing the principle of least privilege.
- Consistent Policy: Inline inspection for all web and private traffic applies one unified policy everywhere, closing security gaps.
- Simplified Management: A single management console streamlines change control, monitoring, and evidence gathering for audits.
The Business Case for CTOs in 2025
Cybersecurity programs are ultimately measured by their ability to reduce risk and improve operational efficiency. Reports on the cost of data breaches consistently show that control maturity and automation significantly affect breach costs and response times. A unified SASE platform delivers value on three critical fronts:
- Lower Likelihood: By enforcing identity-based access and device posture checks, you reduce the probability of a successful breach.
- Lower Impact: Unified telemetry and centralized visibility enable faster threat detection and isolation, minimizing the blast radius of an incident.
- Lower Operating Cost: Consolidating tools and automating routine tasks frees up your IT team to focus on strategic initiatives instead of managing complex infrastructure.
What a Real SASE Platform Should Include
For mid-market organizations and public sector teams in Europe, a workable SASE platform should integrate the following capabilities into a single, cloud-managed fabric:
- Zero Trust Network Access (ZTNA): Provides app-level access with micro-segmentation, verified by user identity and device health.
- Secure Web Gateway (SWG): Delivers category-based URL filtering and real-time threat protection for all web traffic.
- Firewall-as-a-Service (FWaaS): Enforces outbound and inter-site policies with manageable rules and centralized logging.
- SD-WAN: Ensures secure and high-performance connectivity between sites with application-aware routing.
- Device Posture Checks: Verifies device health and identity before granting access to corporate resources.
- NIAC (Network Inline Access Controller): Isolates and onboards agentless assets like printers, IoT devices, and industrial machines that cannot run software agents.
- Network Controllers: Extends the policy fabric to branch offices and industrial plants with virtual, physical, and industrial hardware options.
- API-First Management: Enables automation and seamless integration with identity providers and other IT systems, crucial for MSP operations.
- Transparent Pricing: Offers a predictable, per-user model that simplifies budgeting and helps partners build scalable services.
These capabilities make Zero Trust a default part of your daily operations. A European-based platform also provides assurance regarding data protection and regulatory alignment.
How Jimber Makes SASE Simple
Jimber approaches SASE as a straightforward operating model, not a complex, multi-year project. Our focus is on radical simplicity. We enable rapid rollouts, low day-two operational effort, and clear evidence that maps directly to European compliance rules like NIS2.
Our platform is built with a partner-first mentality, featuring multi-tenant operations from the ground up. A key differentiator is our unique ability to bridge IT and OT (Operational Technology) environments. With NIAC hardware and industrial controllers, we create a safe, auditable connection between corporate networks and production lines without disrupting critical operations.
A Pragmatic SASE Implementation Guide for CTOs
Avoid a “big bang” disruption by following a phased approach. This aligns security improvements with the evidence required for European compliance.
Phase 1: Align and Baseline
- Map user groups, critical applications, and agentless devices.
- Integrate your identity provider and define initial device posture checks.
- Deploy your first network controller in a non-critical network segment.
- Pilot ZTNA for a small group of remote users and internal applications.
Phase 2: Expand Coverage
- Roll out ZTNA to all remote users, enforcing least-privilege access.
- Enable SWG and FWaaS with a default-deny stance for high-risk traffic categories.
- Introduce SD-WAN to replace costly and opaque legacy links where appropriate.
- Onboard agentless devices like printers and IoT sensors using NIAC hardware.
Phase 3: Consolidate and Automate
- Begin retiring legacy VPN concentrators and reducing the scope of on-premises firewalls.
- Use the API to automate common tasks like policy updates and report generation.
- Establish dashboards and reports that map directly to NIS2 and DORA evidence requirements.
- Validate disaster recovery paths for your critical applications and the SASE platform.
Phase 4: Extend and Formalize
- Use network controllers to standardize security across all branch offices and plants.
- Provide partners and contractors with scoped, audited access through ZTNA.
- Formalize service definitions for MSP delivery, including SLAs and incident response runbooks.

Frequently asked questions about SASE
Is SASE the same as SSE?
No. SSE (Security Service Edge) focuses on the security functions like ZTNA and SWG. SASE is broader, including the networking component (SD-WAN) to bring both domains into one unified platform.
Can we keep our existing firewalls?
Yes, especially during the transition. Most organizations gradually reduce the scope and complexity of on-prem firewalls as they move policies to the SASE platform and replace legacy links with SD-WAN.
How does unified SASE help with NIS2 and DORA?
It simplifies compliance by providing unified policies, consistent logs, automated reporting, and identity-based access controls. This makes it easier to demonstrate control effectiveness and meet strict reporting timelines.
What about AI-related breach risks?
Centralized SASE controls reduce your attack surface from unauthorized “shadow IT” tools and help unify detection data. Mature security policies and automation, key benefits of SASE, are proven to enable faster containment of all threats, including those related to AI.
