How do you get CISOs to attend a roundtable event?

Choose a peer discussion topic that CISOs find genuinely useful (AI governance, third-party risk, board communication) — not a vendor showcase. Send a brief, specific invitation (under 80 words) with Chatham House rules and a curated guest list description. This approach converts 8-15% of a well-filtered CISO invite list.

What format works best for a CISO roundtable?

12-20 participants, 45-60 minutes, facilitated by a senior security practitioner or former CISO, with Chatham House rules. Vendor presence should be minimal — hosting and a brief 3-5 minute intro only. The discussion must be CISO-to-CISO.

How do you follow up after a CISO roundtable to book meetings?

Three steps: Day 1 thank-you with discussion summary. Day 3 personal note to the top 5-8 attendees referencing what they said. Day 7 brief direct meeting request from a senior team member. This converts 25-40% of actively engaged attendees to qualified meetings.

What CISO roundtable topics work in 2026?

AI governance for security teams, agentic AI and third-party risk, CISO-board communication on AI exposure, zero trust implementation at different company scales, and IAM priorities. Topics must be triggered by real current challenges — not vendor-defined product categories.

How many CISOs can LinkedOtter put in a single roundtable event?

LinkedOtter generated 38 C-level security contacts including CISOs at a single RSA-adjacent event from a list of 1,266 prospects. A typical curated CISO roundtable targets 12-20 active participants.

How to Run a CISO Roundtable Event That Books Meetings with Cybersecurity Buyers in 2026

What Makes a CISO Roundtable Different From a Security Webinar

A CISO roundtable is not a webinar with better branding. It is a fundamentally different format designed for a fundamentally different buyer. CISOs are among the most senior, most saturated-with-vendor-pitches buyers in B2B. They receive an estimated 60 cold outreach attempts per week. Most are immediately discarded.

What a CISO will actually attend: a private, curated conversation with 10-20 peers on a security challenge they are actively navigating. Not a product demo. Not a thought leadership webinar. A peer discussion where they get something useful — perspective from other CISOs — in exchange for 45-60 minutes.

The roundtable format converts because the offer is peer learning, not vendor content.

Step 1: Choose the Right CISO Roundtable Topic

The topic is 80% of the success of a CISO roundtable. The wrong topic fills no seats. The right topic fills the event with your exact ICP.

Topics that work in 2026 (triggered by real events):

AI governance for security teams: what are other CISOs doing about AI-generated code and LLM access to production systems?
Third-party risk management in the age of agentic AI: how are security leaders reassessing vendor access when AI agents can take autonomous actions?
CISO-board communication in 2026: how are security leaders explaining AI threat exposure to boards that do not yet understand it?
Zero trust in practice: what does it actually look like at a 500-employee company versus a 5,000-employee enterprise?
Identity and access management priorities after three consecutive years of IAM-related breaches

The topic selection rule: Choose a topic where a CISO would think "I would get something useful from hearing what my peers are doing" — not "a vendor wants to tell me about their product."

Step 2: Build the CISO Invite List

CISOs are reachable through a combination of Apollo and Clay enrichment, but the filtering must be precise:

Apollo filters:

Title: CISO, Chief Information Security Officer, VP of Information Security, Head of Security, Director of Cybersecurity
Company size: 200-5,000 employees (adjust for your deal size)
Industry: Match your ICP — financial services, healthcare, SaaS, critical infrastructure
Geography: US (or specific region)

Clay enrichment to add:

Recent security incidents or breaches in their industry (regulatory trigger)
Companies that recently posted a new CISO role (organizational change)
Companies at regulated milestones (HIPAA, PCI DSS, SOC 2 renewal, FedRAMP)
Companies with active security infrastructure job postings (investment signal)

From a list of 1,266 cybersecurity prospects, LinkedOtter generated 38 C-level attendees at a single RSA-adjacent event. That concentration of senior security buyers in one program is achievable with precise targeting and the right topic.

Step 3: Write the Invitation That Gets a CISO to Register

CISOs respond to peer-to-peer framing, brevity, and evidence that the guest list is curated. The invitation should:

Be under 80 words
Describe the exact topic in one sentence
Name the audience (e.g., "CISOs at Series B-D security software companies")
Specify the format (private roundtable, 12-15 participants, 45 minutes, Chatham House rules)
Make the ask to register — not to take a meeting

Subject line: [Topic] CISO roundtable — [date], 12 CISOs registered

That format and subject line converts at 8-15% for a well-filtered CISO list.

Step 4: Run the Roundtable

Format recommendations:

Participants: 12-20 CISOs. Fewer than 12 feels sparse; more than 20 loses the roundtable dynamic
Facilitator: A senior moderator, not a vendor rep. Former CISO or well-known security practitioner works best
Duration: 45-60 minutes maximum
Vendor presence: Limit to hosting and a brief 3-5 minute context-setting at the start. The discussion should be CISO-to-CISO
Ground rules: Chatham House rules (insights shared, sources not attributed) increase candor
Format: Virtual roundtable works well; in-person at conferences (RSA, Black Hat) generates higher engagement

Step 5: Post-Roundtable Follow-Up That Books Meetings

The meeting comes after the event, not during. Post-roundtable follow-up that converts:

Day 1: Thank-you note. Brief summary of the 2-3 most common themes discussed. No pitch.

Day 3: Personal note to the top 5-8 attendees (those who spoke the most, asked questions, or engaged with specific points). Reference what they said or the topic they engaged with most.

Day 7: Direct, brief meeting request from a senior member of your team: "Based on your comment about [specific topic] during the roundtable, I think we could have a useful 20-minute conversation about how we are helping CISOs in similar situations address this."

That three-step sequence converts 25-40% of actively engaged roundtable attendees to qualified meetings.
