Gigamon named 2026 public sector observability leader

Gigamon has been named Frost & Sullivan's 2026 Company of the Year for Global Network Observability for the public sector, as government and education bodies face rising cyber risks and increasingly complex hybrid IT environments.

The award cites Gigamon's work on "deep observability" and its role in providing real-time network visibility across public sector environments. Observability has become a growing focus for government security teams as agencies expand cloud use, adopt container platforms, and manage a mix of modern and legacy systems.

Public Sector Focus

Public sector organisations handle sensitive citizen data and run critical services, often under strict regulatory frameworks and procurement rules. Security teams also frequently contend with fragmented tools across on-premises networks, virtualised environments, and multiple cloud platforms.

Gigamon positions its technology around network-derived telemetry, including packet data, flow records, and application metadata. It says this data can be fed into cloud, security, and observability tools for analysis and response.

The approach is aimed at visibility challenges created by encrypted traffic and east-west activity inside networks. It also aligns with broader moves toward Zero Trust security models, where access decisions rely on continuous validation rather than assumed trust based on network location.

Gigamon's Deep Observability Pipeline is designed to work across physical infrastructure, virtual environments, public cloud, and container deployments, collecting and distributing network telemetry at scale.

Deployment Claims

Gigamon says it is deployed across all 10 of the top US federal agencies, along with hundreds of federal, state, and educational institutions worldwide. It did not provide a country-by-country breakdown or the number of public sector customers outside the US.

Frost & Sullivan's recognition is awarded annually. The firm says the Company of the Year designation reflects growth strategy and execution, alongside innovation, customer value, and market penetration.

In the public sector, network observability is increasingly tied to security operations. Agencies often need to demonstrate compliance controls and audit trails while maintaining availability for systems that support healthcare, emergency response, tax, welfare, and education.

Market Context

Network security teams are also working to reduce blind spots created by encrypted traffic. Encryption is now the default for many applications and services, improving privacy but reducing the effectiveness of traditional inspection methods and increasing reliance on metadata, behavioural signals, and selective decryption.

At the same time, lateral movement within networks remains a common technique in targeted attacks, and hybrid environments can complicate detection. Logs and events may be spread across separate systems with inconsistent schemas and retention policies.

Gigamon's stated focus is delivering network telemetry into other tools, including security platforms and observability products used by IT operations teams. Many organisations already run multiple tools across these domains, and consolidation efforts have increased as budgets come under pressure and leaders seek to simplify operations.

Frost & Sullivan highlighted Gigamon's position in this niche for government customers. "Gigamon has emerged as a foundational technology in public sector cybersecurity, underpinning critical services and national infrastructure with deep observability," said Sujan Sami, Senior Research Director at Frost & Sullivan.

"Consistent delivery of customer value, procurement accessibility, and operational reliability positions Gigamon as a mission-critical partner in global public sector network observability, and the reason they were named the Frost & Sullivan 2026 Company of the Year for Public Sector," Sami said.

Gigamon says its public sector business has operated for more than 20 years and described its current focus as an extension of that work, with greater emphasis on hybrid environments and emerging workloads.

"Gigamon has supported public sector missions for more than two decades by providing the network visibility that underpins cyber resilience for critical government systems," said Dennis Reilly, Vice President of Public Sector at Gigamon. "That experience now powers the Gigamon Deep Observability Pipeline, helping organizations gain complete visibility across data in motion to secure and operate increasingly complex, AI-driven infrastructure."

Gigamon says its technology is used by more than 4,000 organisations globally, including 83 of the Fortune 100, mobile network operators, and public sector agencies. It expects to continue investing in its observability pipeline and public sector partnerships as government security programmes expand and Zero Trust policies mature.
