Zero trust is finally moving from buzzword to actual deployments. Identity and access management tools are getting the most funding. Most investors want to see enterprise contracts and integration with existing security stacks, not just another ZTNA point solution.

Experience: Look for funds that have backed identity or network security companies before. Most generalist VCs think zero trust is just MFA and miss the architecture shift. Find partners who've invested through the VPN to SASE transition. Review our guide on sending decks before outreach.
Network: Ask if they can intro you to CISOs at mid-market or enterprise companies. Zero trust sells top-down through security teams. Distribution partnerships with MDM or SIEM vendors matter more than having a16z on your cap table.
Alignment: Seed investors often don't understand why zero trust takes 12-18 months of enterprise pilots. Security procurement is slow. Make sure they've funded security companies through long sales cycles before.
Track record: Check if their portfolio companies actually have Fortune 500 customers. Zero trust that only works for 50-person startups isn't defensible. Look at whether they supported companies through compliance certifications like FedRAMP or SOC 2 Type II.
Communication: Use Ellty to share your deck with trackable links. You'll see who actually opens your architecture diagrams and integration roadmap slides. Most investors skip the technical details, which tells you they don't understand the product.
Value-add: Generic promises about "our CISO network" usually mean they know two security people. Ask specifically which security vendors or cloud platforms they can connect you to for partnerships. Integration partnerships close more deals than brand name investors.
Identify potential investors: Search Crunchbase for "zero trust," "network security," and "identity" deals from 2024-2025. Seed funds won't lead your Series B, no matter how good your logo retention is. Look at who invested in companies like Tailscale, Zscaler, and Okta early. For founders comparing document-sharing tools during this stage, exploring Docsend-alternatives can help streamline your outreach process.
Craft a compelling pitch: Lead with which zero trust use case you're solving and for whom. Don't spend slides explaining why perimeter security is dead - they know. Show your integrations with existing security stacks. Most investors are tired of "zero trust for X" pitches without showing how you fit into their 15 existing security tools.
Share your pitch deck: Upload to Ellty and send trackable links. Monitor which pages investors spend time on - if they skip your compliance and integration roadmap, that's useful information. You'll know who's serious based on whether they view your technical architecture and competitive differentiation slides.
Utilize your network: Message portfolio founders on LinkedIn and ask about term sheet timelines and actual help during enterprise sales cycles. Most will be honest about whether their investor actually understands security buying processes. Make sure any shared materials follow proper GDPR rules to avoid compliance issues.
Attend networking events: RSA Conference has the most security investors. Black Hat and DEF CON work if you're technical. Skip generic startup events - zero trust investors aren't there. S4 Capital has good European security investors. Before sharing anything post-event, ensure your documents follow secure sending practices.
Engage on online platforms: Connect with partners on LinkedIn after you've been introduced. Cold DMs rarely work for security - it's too technical to explain in a message. Security Twitter can work if you're building in public with technical content.
Organize due diligence: Set up an Ellty data room with your security certifications and penetration test results before they ask. It speeds up the process. Include your compliance roadmap and any design partner agreements with enterprise security teams. Protect sensitive details with our screenshot guard to maintain confidentiality.
Set up introductory meetings: Lead with which zero trust pillar you're solving and current enterprise pipeline. Don't waste 20 minutes on market size slides - they know the TAM for security. Get to your integration strategy and how you fit into existing security stacks quickly.
Remote work and cloud adoption mean perimeter security doesn't work anymore. Companies are finally replacing VPNs with real zero trust architectures instead of just adding MFA.
The Biden administration's 2021 zero trust mandate is pushing government agencies and contractors to adopt zero trust by end of 2026. Investors are backing platforms that can handle federal compliance requirements. Cloud security posture management and identity platforms are seeing the most deal activity.

Upload your deck to Ellty and create a unique link for each investor. You'll see exactly which slides they view and how long they spend on your zero trust architecture and integration diagrams. Most founders are surprised to learn investors skip the market size slides but spend 10+ minutes on technical implementation and competitive positioning.
When investors ask for more materials during due diligence, share an Ellty data room instead of messy email threads. Your architecture docs, security certifications, penetration test results, and design partner agreements in one secure place with view analytics. You'll know when they're actually reviewing your SOC 2 report versus just saying they will.
How do I know if an investor actually understands zero trust versus just the buzzword?
Ask what they think differentiates zero trust from traditional VPNs with MFA. If they can't explain least privilege access or continuous verification, they don't understand the architecture.
Should I cold email zero trust investors or get introductions?
Get intros if possible. Security is technical enough that cold emails rarely work unless you have CISOs from Fortune 500 companies in your pipeline. Warm intros from portfolio CISOs or founders work best.
What's the difference between seed and growth stage zero trust investors?
Seed investors will fund you with design partners and early pilots. Growth investors need to see $3M+ ARR and deployments at mid-market or enterprise accounts with complex environments.
How many investors should I reach out to?
Start with 10-15 that have recent security deals and understand zero trust architecture. Security investors talk to each other, so word gets around if you're shopping a weak product.
When should I set up a data room for zero trust security?
Before first meetings. Investors will want to see your security certifications, pen test results, and compliance status early. Having it ready speeds up diligence by 2-3 weeks.
Do investors actually care about which slides they view in my deck?
Yes. If an investor spends 2 minutes on your deck versus 15 minutes on your architecture and integration slides, you'll know who's serious. It saves time on follow-ups with tire-kickers who don't understand the product.
