Sonar welcomes David Knott as Senior Advisor.

Sonar welcomes David Knott as Senior Advisor. AUSTIN - October 29, 2026 - Sonar, the global leader in agentic code governance and verification, today announced that Dr. David Knott has joined the company as a Senior Advisor. Dr. Knott will advise CEO Tariq Shaukat and Sonar's Product and Go-to-Market leadership on the needs of enterprise organizations adopting AI and agentic software development, bringing more than 30 years of experience across government, financial services, technology consulting, and a range of other industries. As enterprises give AI agents a greater role in software development, they need confidence that the resulting software will meet the demands of their business. That must be built into agentic software factories, with clear requirements guiding agents, independent verification of their work, and evidence that standards are met. Dr. Knott's experience leading technology development and architecture in complex, highly regulated environments will help to inform Sonar's product roadmap and engagement with enterprise customers navigating that transition. Previously, Dr. Knott served as Chief Technology Officer for the UK Government and as Chief Architect at HSBC where he was accountable for all technology design decisions across the organization. He has also held senior roles at Google Cloud, Lloyds Banking Group, Wipro, and Boston Consulting Group. "I'm delighted to have David join the Sonar advisory team. His perspective spans some of the most mission critical and complex technology environments imaginable," said Tariq Shaukat, CEO of Sonar. "Enterprise leaders want to turn AI's potential into business value without increasing operational risk or creating software that becomes harder to maintain. David is a technology leader that understands the complexities involved. I'm excited to have him on the team as we help enterprises use agentic coding with confidence." "The promise of agentic software factories depends on confidence in the software they produce. I have seen firsthand, across financial services and government, the consequences of treating code verification and governance as an afterthought. Sonar is doing something important: helping developers and organizations integrate that confidence into how their agents work, from the start," said Dr. David Knott, Senior Advisor to Sonar. About Sonar Sonar enables organizations to ship agentic code with confidence. Trusted by 75% of the Fortune 100, Sonar reduces outages, improves security, and lowers the cost and risk of agentic software development. SonarQube, Sonar's core platform, verifies over 750 billion lines of code every day, catching bugs, vulnerabilities, and architectural flaws before they reach production. Sonar is relied on for AI code verification and governance by 7M+ developers globally, including teams at Nvidia, ServiceNow, Booking.com, Goldman Sachs, AstraZeneca, and Ford Motor Company. A Gartner(R) Magic Quadrant(TM) Leader[1], Sonar is the essential trust layer for the enterprise agentic software factory.

Sonar brings agentic code governance to self-managed infrastructure with SonarQube Server 2026.5 LTA

Sonar has launched SonarQube Server 2026.5 LTA, bringing its agentic code governance capabilities to self-managed infrastructure. The platform allows enterprises to guide, verify, and resolve issues in AI-generated code on their own infrastructure, including on-premise and air-gapped environments. The release follows GitHub's report that monthly commits grew from 1.4 billion in April to 2.9 billion in August. Sonar's platform includes Sonar Vortex, which verifies code changes in real time and reduces token consumption by up to 36%, and SonarQube Hunter Agent, which identifies security flaws traditional analysis misses. The company recently acquired Gitar, an AI-native code review solution. SonarQube Server 2026.5 LTA is now available for Enterprise and Data Center editions.

Westcon-Comstor and Sonar sign multi-region deal to accelerate partners' AI adoption with trusted code verification.

Westcon-Comstor and Sonar sign multi-region deal to accelerate partners' AI adoption with trusted code verification. Sarah Weston 1 September, 2026 Westcon-Comstor, a global technology distributor specialising in cybersecurity, networking and hybrid cloud solutions, has announced a multi-region distribution agreement with Sonar, a global leader in AI code verification and governance. The partnership provides high-value growth opportunities for channel partners across Europe, the Middle East and Africa (EMEA) and Asia-Pacific (APAC) to help customers securely adopt AI into their software development workflows. The agreement makes Sonar's core platform, SonarQube, available to Westcon-Comstor partners, enabling them to extend their DevSecOps offerings with automated code verification that helps development and security teams identify and remediate security vulnerabilities, exposed secrets and other code issues before software reaches production. According to Sonar research, SonarQube users are 44% less likely to report AI-derived production outages. Additionally, by maintaining code quality with Sonar, users can reduce token usage by 7-8%, with further reductions possible when agents are guided with governed context. As AI agents become more deeply embedded in development workflows, organisations need to maintain the speed benefits of AI without introducing new security risks. Sonar's Agent Centric Development Cycle (AC/DC) methodology gives partners a clear framework for helping customers do so: guide AI agents with the right context and constraints, verify their output through fast, multi-layered feedback loops and resolve issues before they become a production risk. Through this Guide-Verify-Solve approach, partners can help customers build security and governance into AI-assisted development from the outset. Sonar provides automated code analysis that embeds verification directly into AI-driven workflows to reduce outages, improve security and lower costs and risks associated with AI and agentic coding. This gives security and development teams a shared, actionable view of code risk, while supporting faster remediation and stronger governance as software environments become more complex. The company's recent acquisition of Gitar expands its offering with AI code review, giving organisations the benefits of AI-native code review and comprehensive code verification for the highest level of assurance no matter the AI tool. With strong upsell and cross-sell potential, short sales cycles, fast time to revenue and attractive margins, Sonar enables partners to broaden customer relationships and create new recurring revenue streams. Partners will benefit from Westcon-Comstor's value-added distribution model, which supports market entry and growth through technical enablement, market intelligence and data-driven lead generation, alongside support for customer adoption, expansion and renewals. "Sonar is a recognised leader in its field, and this collaboration represents both a compelling commercial opportunity and a strategic technology play for the channel." "The rapid adoption of AI-assisted software development, combined with the shift-left movement, is creating new openings for partners as software quality, governance and security become board-level priorities. At the same time, many organisations are looking to consolidate fragmented development and security toolsets onto a single platform. "By combining Sonar's market-leading solutions with our enablement capabilities, technical expertise and international reach, we're empowering partners across EMEA and APAC to win new customers, expand existing relationships and drive sustainable revenue growth," said Adam Davison, Senior Director, Vendor Acquisition at Westcon-Comstor. "Organisations are embracing AI to accelerate software development, but speed only creates value if teams can trust what gets shipped," said Scott Musson, VP of Worldwide Channel at Sonar. "Westcon-Comstor's global reach, channel expertise and value-added approach make it an ideal distribution partner for expanding Sonar's platform to more customers. Together, we can help partners support organisations as they scale AI and agentic coding with stronger verification, clearer governance and greater confidence in every line of code."
