Building your own cybersecurity list costs 2.3 to 3.6 cents a contact, and the same plan sends the emails.
A prebuilt file is a one-time download that starts going stale the day you buy it. In Lead Finder you choose exactly which cybersecurity contacts go in, add more whenever you need them, and the plan that pays for the credits also sends the emails.
| Way to get the list | What you pay | Cost per contact |
|---|---|---|
| Emailchaser Pro | $97 a month with 5,000 lead credits and 125,000 emails a month included | 2.3 cents |
| Emailchaser Starter | $47 a month with 1,500 lead credits and 5,000 emails a month included | 3.5 cents |
| Emailchaser extra credits | $33 per 1,000 credits, or $20 per 1,000 when you buy 5,000 or more; bought credits never expire | 2.3 to 3.6 cents |

Example campaign and email, invented for this page. The count is real.
Threat data providers, channel partners and security recruiters use cybersecurity company lists to reach the people who build and sell protection.
Cybersecurity companies range from a three-person penetration testing shop to product vendors with hundreds of staff. In a small firm the founder decides on tools, partners and hires. In a product company the head of partnerships or channel decides on resale and integration deals, an engineering vice president picks infrastructure and data sources, and a finance lead signs the larger contracts. Filter by job title for the role you sell to and by company size to separate boutique firms from product vendors.
These are the questions people ask about cybersecurity email lists.
How many cybersecurity contacts can I reach with Emailchaser?
Lead Finder holds 226,243 US people at cybersecurity and data security companies with a verified work email, from a live count on 3 November 2026. The count changes as people change jobs, so the number you see in Lead Finder on the day you search is the one that counts.
Can I filter cybersecurity contacts by state, city or company size?
Yes. Lead Finder filters by country, state and city, by seniority (for example owner, partner or director), by company size from 1-10 employees up to 10,001+, and by job title, revenue and the technology a company uses. Combine them freely, and the count updates before you spend anything.
How much does a cybersecurity email list cost on Emailchaser?
Searching and counting are free. Each person you add uses 1 lead credit. Plans include 1,500 credits a month on Starter ($47), 5,000 on Pro ($97) and 10,000 on Max ($358), and extra credits cost $33 per 1,000, or $20 per 1,000 when you buy 5,000 or more. Checking each address is billed apart from credits, at $0.0017 a check. The 7-day free trial includes 500 lead credits.
Is this list for people who buy cybersecurity or people who sell it?
It counts people who work at cybersecurity and data security companies, who are the sellers. To reach the people who buy security tools, use the CISO list or the IT manager list on this site.
Are the emails verified?
Lead Finder only returns people whose work email has a verified status. When you add them, Emailchaser checks each address again (on by default, $0.0017 a check, one or two checks an address), and an address that fails is dropped without using a credit.
Is it legal to send cold email to cybersecurity contacts?
In the United States, the CAN-SPAM Act allows commercial email to business addresses when you identify yourself honestly, use an accurate subject line, include a postal address and honour every opt-out. Rules are stricter in some other countries, such as under GDPR in Europe.
