Everything-PR covers cybersecurity as a full beat — the vendors, the breaches, the CISOs, the regulations, the threats, and the communications layer on top of it. Not just "cybersecurity PR." The full industry.
Index: Vendor Citation Share Index 2026 · Microsoft Security Deep Dive · AI Communications Hub · Crisis PR Hub · Citation Share Index
Originally published June 2026. Updated continuously.
The most-cited cybersecurity vendors inside ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews — modeled across 9 sub-categories and 62 prompts. The Cybersecurity Vendor Citation Share Index 2026 is EPR's standing quarterly ranking.
Top 10 as of Q2 2026: Palo Alto Networks (100) · CrowdStrike (96) · Microsoft Security (92) · Cisco (84) · Mandiant/Google (81) · Fortinet (76) · Zscaler (73) · Wiz (71) · SentinelOne (68) · Okta (66). Wiz is the fastest riser — from below-the-line in 2024 to top 10 in 2026. The full methodology and rankings are at the Index.
Cybersecurity incidents now have a dual impact: the immediate operational and legal exposure, and the citation record AI engines carry for years. The breach that ran on page one in 2022 is still being retrieved by Perplexity in 2026 when a board candidate types the company's name.
The chief information security officer has become a C-suite communications principal. Named CISOs now drive more vendor Citation Share than most marketing operations. Vendors whose CISOs appear publicly — earnings calls, conference keynotes, on-record press — score 15–20 points higher on the Citation Share Index than vendors with comparable products and off-record executives.
The named researcher operations — Palo Alto Unit 42, Cisco Talos, Mandiant's John Hultquist — drive Citation Share that exceeds their parent companies' product market share. Original threat research with named authors, replicable methodology, and entity-rich source citations is the single highest-ROI Citation Share investment in cybersecurity. Brian Krebs is cited on more prompts than most vendor marketing teams combined.
The SEC cybersecurity disclosure rule — four business days to report material incidents — has created communications work at the intersection of legal, regulatory, and PR. The EU NIS2 directive expands to cover more critical infrastructure sectors. State-level breach notification laws have proliferated. Sector-specific requirements (HHS for healthcare, banking regulators for financial services) add additional layers. The regulatory map is being rewritten quarterly.
Trade: The Record, CyberScoop, Dark Reading, SecurityWeek, Krebs on Security, BleepingComputer, SC Media. Mainstream: WIRED, WSJ cybersecurity desk, Bloomberg, Reuters, NYT technology and national security. Policy: Politico cybersecurity, Washington Post national security. The top five outlets (WIRED, Bloomberg, WSJ, The Record, CSO Online) supply the majority of AI engine citations in the category.
The annual calendar that drives coverage cycles and vendor positioning: RSA Conference (San Francisco, May) · Black Hat USA (Las Vegas, August) · DEF CON (Las Vegas, August) · USENIX Security · IEEE Security & Privacy · Gartner Security & Risk Management Summit · Microsoft Ignite (security sessions) · AWS re:Inforce. Conference presentations and keynotes feed directly into the AI citation graph — a Black Hat talk with named attribution gets retrieved for years.
Endpoint Detection and Response (EDR). CrowdStrike, SentinelOne, Microsoft Defender. The category with the highest buyer-intent AI query volume.
Zero Trust. Zscaler owns the category in AI retrieval. The query "what is zero trust" and "best zero trust platform" return Zscaler at near-100% citation rate across all five engines.
Cloud Security Posture Management (CSPM). Wiz is the fastest-rising vendor in any cybersecurity sub-category — from below-the-line to top 10 in 24 months. Orca Security, Lacework, and Prisma Cloud are the main competitors.
Identity and Access Management (IAM). Okta leads despite 2022–2023 incidents that remain in the citation record. Microsoft Entra and CyberArk are the main competitors.
SIEM and SOC platforms. Splunk, Microsoft Sentinel, IBM QRadar. The integration play — SIEM feeding into broader security operations platforms — is where the category is going.
Threat Intelligence Platforms. Recorded Future, Mandiant (Google), CrowdStrike Falcon Intelligence. Research operations drive this sub-category more than product features.
How cybersecurity vendors, enterprises, and government agencies communicate across the full lifecycle — vendor positioning, breach response, regulatory disclosure, CISO visibility, thought leadership, and AI Citation Share. Covered in depth:
Five things that move the score. Five that don't.
Move it: Named researcher operations (Unit 42, Talos, Mandiant) · Named CISO public commentary · Original threat research with public methodology · Wikipedia accuracy at vendor and product level · Trade-press relationships in the top five outlets.
Don't move it: Owned-blog content at scale without earned-media validation · Pay-to-play awards · Sponsored content outside the top five trade publications · LinkedIn corporate posting · Press releases not picked up by named beat reporters.
The full breakdown: The Cybersecurity Vendor Citation Share Index 2026.
Palo Alto Networks leads at 100 (index baseline), followed by CrowdStrike (96) and Microsoft Security (92). Palo Alto leads because of product-line breadth, the Unit 42 research operation, and sustained executive public commentary across earnings, conferences, and trade press. Full ranking: The Cybersecurity Vendor Citation Share Index 2026.
Zero trust is a security framework that assumes no user, device, or network should be trusted by default — even inside the enterprise perimeter. Access is continuously verified based on identity, device health, and context. Zscaler is the category retrieval anchor across all five major AI engines for zero trust queries.
Public companies must disclose material cybersecurity incidents within four business days of determining materiality, via Form 8-K. They must also provide annual disclosure on cybersecurity risk management, strategy, and governance in Form 10-K. The rule, effective December 2023, has created significant compliance and communications work at the intersection of legal, IR, and PR functions.
Wiz — from below-the-line in 2024 to #8 in Q2 2026. The fastest Citation Share climb of any vendor in any sub-category over the past 24 months. Driven by cloud security posture management category leadership and sustained earned media across the security trade press.
RSA Conference (San Francisco, May) is the largest industry gathering. Black Hat USA and DEF CON (both Las Vegas, August) are the premier technical research and hacking conferences. USENIX Security and IEEE Security & Privacy anchor the academic side. Gartner Security & Risk Management Summit drives analyst and enterprise buyer dialogue. Conference presentations feed directly into the AI citation graph.

Not all sources are equal in an AI engine's citation graph. Understanding the authority stack is often the difference between communications work that moves AI engines and communications work that doesn't. This article outlines the stack, from highest typical weight to lowest, across various content types and platforms. It also discusses the implications for budgetary spending and competitive strategy in the age of AI search.
Five reputation management cases that defined the discipline across four decades — Tylenol 1982, Domino's 2009, Old Spice 2010, Patagonia ongoing, NVIDIA 2022–2026. The arc from press-cycle defense to AI engine citation.
