How many cybersecurity buyers should you invite to fill a 30-person event?

Aim for 300-800 targeted invites to fill a 25-40 person cybersecurity practitioner event. Expect 5-10% registration from a well-targeted list and 50-65% show rate from registrants.

What makes a CISO event invitation convert?

A 3-4 sentence invitation with no product mention. Name the specific topic, a peer practitioner speaker, and who else will be in the room. CISOs respond to peer-validated conversations, not vendor pitches. The invitation must read like outreach from a peer, not a BDR sequence.

Can you use Apollo sequences for cybersecurity event invites?

Yes. A 3-touch Apollo sequence works: invitation email, 3-day follow-up with relevant context, 5-day final send noting available spots. Supplement with personal LinkedIn DMs from a named contact for two-channel presence.

How does LinkedOtter use Apollo for cybersecurity event outreach?

LinkedOtter uses Apollo to build the ICP invite list, applies intent and technographic filters to identify the highest-fit accounts, and supplements email outreach with personal LinkedIn DMs. Clients have reached 38 C-level security leaders from 1,266 targeted prospects at events like RSA.

Creating Event Invites for Cybersecurity Buyers with Apollo in 2026

Q: What Apollo filters work best for cybersecurity event invites?

Filter by title (CISO, VP Information Security, Head of SOC, Director of Cyber Risk), company size (500-10,000 employees), industry (financial services, healthcare, critical infrastructure, SaaS), and geography. Layer in intent signals and technographic filters to narrow from 10,000 to your top 300-800.

Creating event invitations for cybersecurity buyers with Apollo in 2026 means using Apollo''s search and enrichment capabilities to identify the right CISOs, VPs of Security, and SOC leaders, then sending an invitation that feels nothing like the vendor emails already filling their inbox.

Here is the full approach.

Who Are the Right Cybersecurity Buyers to Invite to a B2B Event?

The core cybersecurity buyer persona for most vendors includes:

CISO (Chief Information Security Officer): budget authority for enterprise security tools, skeptical of vendors, responds to peer peer-validated conversations
VP of Information Security: operational decision-maker, evaluates tools against compliance and integration requirements
Head of Security Operations (SOC): focused on threat detection and response tooling, interested in practitioner-level conversations about what actually works
Director of Cyber Risk / GRC: cares about compliance, regulatory frameworks, and risk quantification

For most cybersecurity vendors, the event audience should be 60-70% CISOs and VP-level, 30-40% Director-level security leaders.

How Do You Filter for Cybersecurity Buyers in Apollo?

In Apollo''s people search:

Title filters: CISO, Chief Information Security Officer, VP of Information Security, VP of Security, Head of Security Operations, Director of Cyber Risk, Director of GRC, Head of SOC

Company size: 500-10,000 employees (enterprise security buyers with budget authority)

Industry: Financial services, healthcare, critical infrastructure, SaaS (above $50M ARR), government contractors

Seniority: Senior, Director, VP, C-Suite

Geography: United States (or your target region)

This initial filter will typically return 5,000-20,000 contacts. The next step is narrowing to your highest-fit ICP.

How Do You Narrow the Apollo List for a Cybersecurity Event?

Layer in intent signals. Apollo''s intent data shows which companies are actively researching security tools. Prioritize accounts showing intent for the category your event covers.

Filter by technographic. If your event is about AI-powered threat detection, prioritize accounts that already have SIEM, EDR, or cloud security tools in their stack. They are more likely to be evaluating additions.

Company news signals. Filter for accounts that have had a recent security incident (via news), a new CISO hire in the past 90 days, or a recent funding event. These companies are in an active evaluation cycle.

Aim for a final invite list of 300-800 contacts. This is enough to fill a 30-60 person event with proper follow-up.

What Does a High-Converting Cybersecurity Event Invitation Look Like?

The invitation must not read like a vendor email. CISOs have seen every version of the vendor pitch sequence.

A high-converting invitation for a cybersecurity practitioner event:

Subject: [Topic] roundtable with [X] CISOs from [industry], [Date]

Body (3-4 sentences): "We are hosting a small practitioner session on [specific topic, e.g., evaluating AI-powered vulnerability detection tools without expanding your attack surface]. [Speaker name] from [peer company] will be presenting their approach. We have [X] CISOs from [relevant industries] confirmed. Would you join us?"

No product mention. No pitch. One clear value statement.

How Do You Send the Invitation From Apollo?

Apollo''s sequences allow you to set up a 3-touch invitation campaign. Touch 1: the invitation email above. Touch 2 (3 days later): a one-line follow-up with a relevant piece of context. Touch 3 (5 days after touch 2): a final send noting the event date and available spots.

LinkedOtter supplements Apollo email with personal LinkedIn DMs from a named contact. The combination of email and personal LinkedIn creates a two-channel presence without feeling like a sequence.

How Many CISOs Should You Expect to Attend?

From a list of 500-800 targeted cybersecurity invites, a well-run event invitation campaign typically generates a 5-10% registration rate and a 50-65% show rate.

That means 25-52 registrations and 13-34 attendees from a 500-person invite list.

LinkedOtter brought 38 C-level security leaders from 1,266 prospects at RSA Conference using this approach. The quality of the invite list determines the quality of the room.
