What Is an InfoSecurity Europe 2026 Attendee List?

An InfoSecurity Europe 2026 attendee list is a verified database of cybersecurity professionals attending the event at ExCeL London, June 2-4.

This isn't a generic contact dump. It's a list of people who've publicly confirmed they're going, either by posting on LinkedIn about registering, sharing that they're speaking, or tagging Infosecurity Europe in a conference prep post. That distinction matters. A lot.

I've seen SDR teams blast 500 "cybersecurity contacts" from a purchased database and get a 0.3% reply rate. Meanwhile, a team with 80 verified attendees who referenced specific sessions hit 12%. The difference? Relevance. When someone knows you know they're attending, the email stops feeling like spam.

InfoSecurity Europe is the largest dedicated cybersecurity event in Europe, according to Infosecurity Europe's official site. Over 15,000 professionals walk that floor. 400+ exhibitors. 200+ speakers across stages covering everything from post-quantum cryptography to ransomware economics. For B2B sales teams selling security tools in EMEA, this is the event.

The definition sounds dry on paper, but in practice a verified InfoSecurity Europe attendee list is the single highest-intent B2B dataset you can get your hands on for EMEA cybersecurity buyers, because every name on it is attached to a public signal that the person has already committed time, travel, and budget to this specific show.

The Short Version

• InfoSecurity Europe 2026 runs June 2-4 at ExCeL London, with 15,000+ attendees and 400+ exhibitors
• The best pre-show outreach window is 2-4 weeks before the event (mid-May), but you should start building your list now
• Segment your outreach by persona: CISOs need strategic messaging, security engineers want technical depth, compliance officers care about frameworks
• Email subject lines that reference specific sessions or themes (AI threats, post-quantum crypto, ransomware) outperform generic "meeting at the show?" lines
• WhoGoes provides verified attendees from LinkedIn posts. Preview 5 free at the InfoSecurity Europe 2026 page

Who You're Reaching: InfoSecurity Europe Attendee Segments

Not everyone at InfoSecurity Europe buys the same way. Not even close.

The attendee mix breaks into five distinct segments, and your email copy should shift for each one. I've mapped out the personas based on previous years' attendee data and what the 2026 program tells us about who's showing up.

The 2026 program's emphasis on AI-powered threats and post-quantum readiness signals that leadership attendees will be thinking about future-proofing, not just current-year firefighting. Your messaging should match that mindset.

Segmentation is the whole game here, because an InfoSecurity Europe DPO who is worrying about NIS2 audit trails and a SOC manager who is worrying about detection latency on a new EDR rollout are technically at the same event but are functionally shopping in two completely different aisles of the same store.

Outreach Sequences Built for InfoSecurity Europe

Generic "will you be at the show?" emails are everywhere. They get ignored. What works is tying your outreach to something specific about InfoSecurity Europe 2026.

Below are three email sequences, one for each major persona. Steal them. Adapt the bracketed sections to your product.

Sequence 1: For CISOs and Security Leadership

Email 1 (4 weeks pre-show): The Strategic Hook

Subject: Post-quantum prep before InfoSecurity Europe?

Hi [First Name],

Noticed you're heading to InfoSecurity Europe in June. With Rik Ferguson's session on why organizations can't afford to wait on post-quantum cryptography, it's clear the conversation is shifting from "if" to "how fast."

We've been working with [similar company type] on [specific outcome]. I'd love 15 minutes at ExCeL to show you what we've found.

Worth a chat?

[Your name]

Email 2 (2 weeks pre-show): The Follow-Up

Subject: Quick question re: your InfoSec Europe schedule

[First Name], following up. I know your calendar is filling up for June 2-4.

If post-quantum isn't your top priority right now, I'm also hearing a lot of CISOs talk about [related pain point your product addresses]. Either way, happy to grab 15 minutes.

I've got [specific resource] I can share ahead of time so the conversation isn't cold.

[Your name]

Sequence 2: For Security Engineers and Architects

Email 1 (3 weeks pre-show): The Technical Angle

Subject: Zero trust at InfoSecurity Europe, theory vs. reality

Hi [First Name],

I saw you're attending InfoSecurity Europe. The AI & Cloud Security stage has some interesting sessions this year, especially around zero trust implementation and cloud workload protection.

We've been working on [specific technical capability]. It's not another dashboard. It's [one-sentence differentiator].

If you're evaluating tools in this space, I can walk you through a live demo at ExCeL. 20 minutes, no slides.

[Your name]

Email 2 (1 week pre-show): The Proof Point

Subject: Re: InfoSec Europe demo

[First Name], one more thing before the show.

[Customer name] deployed [your product] in [timeframe] and saw [specific metric]. I can share the full case study, or just show you the architecture at the booth.

Booth [number], or I can meet wherever works for you.

[Your name]

Sequence 3: For Compliance and GRC Professionals

Email 1 (3 weeks pre-show): The Regulatory Hook

Subject: NIS2 readiness, where do you stand?

Hi [First Name],

With NIS2 enforcement tightening across the EU, a lot of the compliance track at InfoSecurity Europe 2026 is focused on readiness gaps. Are you still building your audit framework, or are you looking for tools to automate what you've got?

We help [type of company] with [specific compliance capability]. I'd love to compare notes at ExCeL.

Subject Lines That Reference InfoSecurity Europe Themes

Subject lines are where most pre-show emails fail. Too vague, too salesy, or too obvious ("Meeting at InfoSecurity Europe?"). The best performers reference something specific about the event.

The 2026 program gives you plenty of material. Shlomo Kramer (founder behind Check Point, Palo Alto Networks, and Cato Networks) is keynoting on cybersecurity investment trends. Cynthia Kaiser, former FBI Cyber Division leader, is covering ransomware economics. Rik Ferguson is tackling post-quantum urgency.

Use those themes. A few examples:

For AI/cloud security buyers:

• AI threat landscape before InfoSec Europe, quick question
• Ron Leizrowice's cloud update at InfoSec Europe, related to what we're building
• Cloud security posture at ExCeL, 15 min?

For ransomware/threat intel buyers:

• Cynthia Kaiser's ransomware session, and what we see on the defense side
• Dark web intel at InfoSecurity Europe, your take?
• Ransomware response before June 2

For post-quantum/crypto buyers:

• Post-quantum prep: starting before or after InfoSec Europe?
• Rik Ferguson's quantum talk, curious where you land
• Cryptographic transition, ExCeL coffee chat?

For leadership/strategy buyers:

• Shlomo Kramer's keynote and your security roadmap
• Vendor consolidation trend at InfoSec Europe 2026
• 15 min at ExCeL to talk [specific outcome]

One pattern that works well: name-drop a speaker or session in the subject, then pivot to your product's relevance in the body. It shows you did your homework. Most vendors don't bother.

Your Week-by-Week InfoSecurity Europe Outreach Calendar

Timing is everything. Too early and you're noise. Too late and calendars are locked. This calendar assumes the event runs June 2-4, 2026.

Start early. Stop late. The teams that build pipeline at InfoSecurity Europe are the ones that treat the calendar above as a hard-running campaign that begins eight weeks out and keeps cadence through the week after the show closes, instead of a two-email scramble jammed into the final fortnight before ExCeL opens.

Personalizing by What They Posted

This is where LinkedIn-verified attendee data gets interesting. When you know someone posted "Excited to attend InfoSecurity Europe 2026, especially the AI & Cloud Security stage," you don't need to guess their interests. They told you.

Some personalization plays I've seen work:

• Session-mention personalization: "I saw you're interested in the AI & Cloud Security track at InfoSec Europe. We're presenting something related, want a preview before the show?"
• Speaker-mention personalization: "Noticed you shared Shlomo Kramer's keynote announcement. His perspective on security investment cycles aligns with what we're seeing at [your company]."
• Theme-based personalization: If someone posts about ransomware defense or NIS2 compliance alongside their InfoSec Europe mention, that's your hook. Use it.

The difference between "I saw you're attending InfoSecurity Europe" and "I saw you're interested in post-quantum cryptography at InfoSecurity Europe" is enormous. One is a form letter. The other is a conversation.

Not every attendee posts publicly, obviously. Your mileage may vary depending on the persona. CISOs post less frequently than vendor-side folks. But when they do post, the signal is gold.

Use what they give you. Read the post first. When an InfoSecurity Europe attendee has already told the entire LinkedIn feed which stage they care about, which speaker they are excited to hear, or which regulatory headache is keeping them up at night, any cold email that ignores that public signal and opens with a generic "hope you are well" line is leaving obvious money on the table.

How InfoSecurity Europe Compares to Other Cybersecurity Events for Outreach

If you're deciding where to focus your pre-show effort, context helps.

InfoSecurity Europe punches above its weight for EMEA-focused teams. The attendee base is more concentrated and, frankly, less over-solicited than RSAC 2026's crowd. I've talked to SDRs who say their InfoSec Europe reply rates beat RSAC by 2-3x, partly because fewer US-based vendors run pre-show campaigns targeting London.

If you're selling into European enterprise accounts, this is your show. Full stop.

Pick your battles. EMEA-focused cybersecurity vendors with limited event budget almost always get better return on effort by running a disciplined eight-week outreach campaign into InfoSecurity Europe than by spreading the same spend thinly across three different US shows where the buyer audience barely overlaps with their actual pipeline.

Getting Your InfoSecurity Europe 2026 Attendee List

So how do you actually get the list? I won't rehash every method here (for the full breakdown, see How to Get a Trade Show Attendee List in 2026). But the short version: most event organizers don't sell attendee lists (and the ones who do are usually repackaged registration data), and manually searching LinkedIn takes hours for maybe 30-50 contacts.

WhoGoes takes a different approach. It surfaces InfoSecurity Europe 2026 attendees from public LinkedIn posts where professionals mention, tag, or discuss the event. You get verified names, job titles, companies, email addresses, and the LinkedIn post itself as proof of attendance. Unlike purchased contact databases, every record ties back to a public signal that this person is actually going.

LinkedIn-verified contacts change the whole equation for InfoSecurity Europe outreach, because every name you preview through WhoGoes comes attached to a timestamped public post you can reference in the first line of your email, and that single detail is usually the difference between a reply rate that justifies the next pre-show campaign and a reply rate that gets the whole experiment quietly shelved.
