Market to CISOs with proof, not fear. Name one specific risk you reduce, show evidence a security team can check, and let them test it in their own environment before they buy. Then give the CISO what they need to defend the purchase to a CFO and a board.

Security leaders are sold to constantly, and most pitches sound alike: a breach statistic, a scary headline, a claim to stop everything. A seed-stage company wins by being specific and checkable where everyone else is loud.

Why selling security is different

Security is one of the few categories where the buyer’s own job depends on the vendor. If a product fails, the CISO answers for it, to the CEO, to the board and, in a public company, possibly in a disclosure. That makes security buyers cautious, skeptical of claims and slow to trust new vendors.

Three features of the market follow from that:

• Claims are tested, not believed. Buyers expect to verify what you say in their own environment, or through independent evidence.
• Your security is part of your product. A vendor with weak security practices is itself a risk, so buyers review you before they review your features.
• Decisions are shared. Security, IT, finance, legal and procurement all weigh in, and each needs something different from you.

The good news for a startup: these buyers reward specificity and honesty, which a small company can offer better than a large one.

The framework at a glance

This guide works through five steps:

1. Understand the pressure the CISO is under.
2. Lead with one risk and one proof.
3. Make your own commitments public.
4. Let them test it.
5. Arm the CISO for the CFO and the board.

Figure 1 shows the people involved in a typical security purchase, and what each needs.

Step 1: Understand the pressure the CISO is under

The CISO’s job has become more visible and more constrained at the same time.

• Budgets are tight. In ISC2’s 2025 workforce study of 16,029 cybersecurity professionals, surveyed in July and August 2025, 36% said their organization had cut security budgets, and 39% reported hiring freezes.^[1]
• Skills are short. In the same study, 59% reported critical or significant skills shortages on their team, up from 44% in 2024.^[1]
• Boards ask more. Since the SEC’s 2023 rule, US public companies must describe in their annual 10-K how they assess and manage material cybersecurity risk and how the board oversees it, and disclose a material incident within four business days of deciding it is material.^[2]

What that means for your marketing: a CISO with a flat budget and a short-staffed team will rarely buy another tool that needs care and feeding. Products that reduce work, or replace something, have an easier path than products that add a console.

Example Co., step 1 Fictional

Example Co. sells software that finds unused admin accounts in cloud tools. Its first homepage said “Stop breaches before they start.” It now says “Find and remove the admin accounts nobody uses, in a day, without an agent.” The second version names a risk, a time and a cost in effort.

Step 2: Lead with one risk and one proof, not fear

Fear-led copy is the default in security marketing, and buyers discount it. Replace it with three things a security team can check:

1. The risk you reduce, in their words. “Stale admin accounts in SaaS tools”, not “identity threats”.
2. What it takes to run. Deployment time, agents or no agents, permissions needed, who maintains it.
3. Evidence. Independent test results, documentation, a public security page, references from named roles.

Be careful with independent test results. MITRE’s ATT&CK Evaluations, for example, publish how products behaved against emulated attacks. Forrester’s Allie Mellen warned in December 2024 that vendor claims of “100%” on the evaluations usually rest on cherry-picked results, unrealistic product settings, or treating the evaluation as a competition, and advised using the results to learn about products rather than to rank them.^[3] If you cite a test, cite what it measured and link the full results.

Your own security posture is part of the proof. Expect the buyer to ask for your SOC 2 report, your security questionnaire answers and your vulnerability disclosure policy before they read your case studies. My post on making security a selling point covers the trust page, and the Security Questionnaire Answer Library helps you answer once and reuse.

Step 3: Make your own security commitments public

A security company that publishes its own security commitments has an advantage over one that doesn’t. In 2024, CISA’s Secure by Design pledge asked software makers to commit publicly to seven goals, including multi-factor authentication, default passwords, security patches, a vulnerability disclosure policy and CVEs; 68 companies signed at launch.^[4] CISA now marks that announcement as archived, so treat the pledge as a useful checklist rather than a current program to join.

Whether or not you sign anything, publish:

• a vulnerability disclosure policy and a contact for researchers;
• how you handle customer data, and where it is stored;
• your incident notification commitment to customers;
• the date of your last penetration test and audit.

An incident write-up published the same day Real example

When Cloudflare had a major outage on November 18, 2025, its CEO, Matthew Prince, published a detailed post-mortem that day. It explained the cause, apologized (“We are sorry for the impact to our customers and to the Internet in general”) and listed four follow-up changes.^[5] Security buyers read write-ups like this as evidence of how a vendor behaves on a bad day. A startup can do the same at its own scale: a short, honest incident note, sent quickly, with what you’re changing.

Step 4: Let them test it before they buy

Security buyers want to see the product work on their own systems. Plan the proof of value as carefully as the website:

• Define success up front. Agree two or three measurable outcomes with the security team before the trial starts: “find all unused admin accounts in our three main SaaS tools within five days”.
• Keep it short. Two to four weeks, with a named owner on each side.
• Do the work for them. Remember the staffing numbers in Step 1: a trial that needs a week of their engineers’ time will stall.
• End with a readout. A one-page result the CISO can forward to a CFO: what was found, what it would have cost, what changes after purchase.

My guide to choosing between a free trial, freemium and a demo covers when a proof of value beats a self-serve trial.

Step 5: Arm the CISO for the CFO and the board

The CISO is rarely the only decision-maker. Finance, IT, legal and sometimes the board will weigh in. Give your champion:

• a one-page business case in money and hours, not threat levels;
• the risk the purchase addresses, mapped to the language their board already uses;
• answers to procurement’s standard security and privacy questions;
• references from peers at similar companies.

Peers matter in security. CISOs talk to each other, in person and in closed communities. Earn your way into those conversations by being useful (sharing research, speaking with practitioners, sponsoring well-run local groups), not by buying a booth and scanning badges. My piece on the B2B buying committee covers how to equip a champion through a group decision.

Common mistakes

• Fear-led headlines. “Breaches cost millions” is on every competitor’s site. Name the specific risk you remove instead.
• ”Stops 100% of attacks.” No security buyer believes it, and it invites scrutiny you can’t pass.
• Hiding your own security posture. If your trust page is thin, buyers assume your product is too.
• Open-ended trials. Without agreed success criteria, a trial drifts and dies. Define the outcome and the end date first.
• Ignoring the CFO. A CISO who can’t explain the purchase in money and hours will struggle to get it approved.
• Selling to the CISO only. Engineers who will run the product, and procurement who will vet you, can each stall a deal.
• Buying attention instead of earning it. Booth scans and cold sequences rarely move security buyers. Useful research and practitioner relationships do.

A checklist before you launch to security buyers

• The homepage names one specific risk, the buyer and what it takes to run.
• A public trust page shows audits, penetration-test dates, data handling and the incident process.
• A vulnerability disclosure policy is published, with a contact.
• Standard security questionnaires are answered and ready to send.
• Any independent test result you cite links to the full results.
• A proof-of-value plan has defined success criteria and a two-to-four-week end date.
• A one-page business case template is ready for the champion.
• Two or three reference customers have agreed to speak to prospects.

How to measure whether it’s working

• Trial-to-purchase rate for proofs of value with agreed success criteria, against those without.
• Time in security review, from questionnaire received to approval. A good trust page and answer library shorten it.
• Win rate by entry point: design partner, referral, inbound content or outbound.
• Deals lost to “no decision”. In security, these often mean the champion couldn’t build the business case. Fix the material, not the pitch.
• Inbound from practitioner content, such as research, talks and community, against paid channels.

Examples from different fields

The approach is the same, one specific risk and checkable proof, but the risk and the proof differ by product. These examples are fictional and illustrative.

AI security startup (protecting company data in AI tools). The risk: employees pasting customer data into public AI assistants. The proof: a two-week read-only trial that reports what was shared, by which team, without blocking anyone yet. The trust question to answer first is where the product itself sends that data.

Email security for mid-sized companies. The risk: invoice and payment-change fraud. The proof: a retroactive scan of the last 30 days of email, with the suspicious messages the current filter missed. The readout is in money (invoices at risk), not threat counts.

Healthcare security vendor. The buyer is a hospital CISO with a small team and strict patient-data rules. Expect to sign a business associate agreement before the trial. Lead with what the product does without touching patient records, and how it fits the hospital’s existing tools.

Security for schools (EdTech). The buyer is often a district IT director, not a CISO, with a tight budget and student-privacy obligations. Price for districts, offer a no-install trial, and show the student-data agreement up front. My guide to selling EdTech to school districts covers the buying calendar.

Industrial security (factories and utilities). Operations teams fear downtime more than breaches. The proof is a passive monitoring trial that never touches the production network, and the message is “see every device on the plant network without risking the line”.

Developer security tools. Engineers decide first, the CISO approves later. Free scanning for open-source projects and clear documentation earn adoption. Then a security dashboard gives the CISO the reason to buy for the whole company.

What changes by stage?

• Seed — Design partners and founder-led selling; one sharp risk, a short proof of value, a public security page.
• Series A — Case studies by role and industry, independent testing if your category has it, a repeatable proof-of-value plan.
• Series B — Analyst relations, partner channels (resellers and managed security providers), and content for the board-level buyer.
