Many solution providers are charting a path of reimagining SASE services, and it is a logical evolution. With the rapid adoption of agentic AI applications and proliferation of corresponding workloads, SD-WAN and security will have to support the requirements of both human users and agents. It is anticipated that agents will generate far more network traffic than humans through persistent, around-the-clock MCP server, API, task, and orchestration calls across the infrastructure. These demands are expected to continue to escalate over time, and infrastructure providers will have to keep pace with deployments in both the cloud and on-premises as private AI adoption grows.
To address these challenges, Fortinet recently announced an expansion of its firewall portfolio with the FortiGate 1200G series, anchored by a broader convergence with the company’s FortiSASE portfolio and SASE Outpost capabilities. This LoneStar Advisory & Research note will dive deeper into these elements, providing insights related to Fortinet’s convergence strategy and what it could deliver to organizations.
FortiGate 1200G – Optimizing Networking And Security For AI Infrastructure
Fortinet believes that the convergence of firewall and SASE technologies can address the complexities of hybrid AI deployment scenarios and deliver resilient connectivity and hardened security. It is a logical thesis. AI application traffic is exploding, encryption overhead is taxing connectivity infrastructure, and hybrid deployments, including cloud and on-premises private AI, must all be comprehended to eliminate bottlenecks and mitigate security vulnerabilities. Furthermore, the ability to flexibly adapt to determine security control points based on data sovereignty and compliance must also be comprehended.
The FortiGate 1200G series of firewalls is designed to support these requirements. Featuring custom FortiASIC silicon and the company’s FortiOS, these new firewalls accelerate network and security processing to meet the demands of modern AI. The solution also provides flexibility for 10G, 25G, and 100G connectivity, providing headroom for both present and future agentic applications and workloads. The resulting benefits are notable – the ability to fine-tune application performance, anticipate future needs across campuses, branches, and data centers, strengthen overall infrastructure resilience and business continuity, and simplify network and security operations.
Fortinet SASE Outpost – Purpose-Built for Sovereignty
With the hybrid nature of agentic AI workloads and applications, organizations require a greater degree of flexibility for security inspection and enforcement. Fortinet’s vision of the convergence of the firewall and SASE services is designed to address this challenge, and the company is also anticipating future customer needs. As private AI adoption grows, Fortinet is offering its SASE Outpost as a flexible deployment feature with the FortiGate 1200G firewall series that extends cloud-delivered SASE enforcement and data processing directly into an on-premises environment while remaining centrally managed from the cloud. It inspects and processes traffic locally, instead of a public cloud point of presence, to manage data residency within the same management plane. Additionally, with FortiGate configured as a SASE Outpost within a customer-controlled environment, it can also act as a SASE point of presence directly.
These are a compelling set of features. Highly regulated industries can take advantage of the benefits of cloud management, while ensuring data and infrastructure sovereignty through a local breakout. This architectural design facilitates dramatically improved visibility and the consistent application of zero-trust security policies across both cloud-delivered and customer-controlled-environments. It also does not come at a trade-off in performance.
Final Thoughts
SASE services will have to evolve to meet new network capacity and runtime security demands. Organizations should not have to choose between the scalability of cloud-delivered security and the performance, control, or sovereignty of on-premises enforcement. The convergence of these models is creating a meaningful new SASE firewall market.
LoneStar Advisory & Research believes that Fortinet is well-positioned to anticipate this AI-fueled shift, enabling customers to apply security through the convergence of its FortiGate firewall portfolio and cloud-delivered FortiSASE, or locally with SASE Outpost, providing operational flexibility while still delivering consistent policy, visibility, and user application experiences. Availability of the FortiGate 1200G is expected later in calendar Q3 2026.
