Verified company records
Security vendors, MSSPs, MDR providers, consultancies and boutique specialists, each classified by primary security category.
A verified cybersecurity companies email list covering 14,600+ security vendors, MSSPs and consultancies, with 72,000+ named contacts inside them. Filter by security category, company size, seniority and region, then reach CISOs, security architects and SOC leaders directly instead of guessing at a shared inbox.
The cybersecurity contact database used by SaaS vendors, channel teams, recruiters and event organizers selling into the security market
Cybersecurity companies build and operate the tools and services that keep organizations safe from attack, from firewalls and endpoint agents through to round-the-clock monitoring. Buyers search for them for very different reasons. Some are shopping for a vendor after a breach or a failed audit. Some are researching a market before investing or partnering. Plenty are salespeople trying to reach the security industry itself. The market divides into recognisable segments: network security, cloud security, endpoint protection, identity and access management, application security, email security, data security, threat intelligence, managed detection and response, and managed security services. The companies below span those segments and several countries. BizzContacts supplies the verified contacts behind them, plus thousands of smaller firms no public list covers.
| Company | Headquarters | Primary Security Focus | Company Type | Overview |
|---|---|---|---|---|
| Palo Alto Networks | Santa Clara, CA, USA | Network and cloud security | Public platform vendor | Grew from a next-generation firewall company into a broad platform spanning network, cloud and security operations. Buyers usually meet it during firewall refresh cycles and then evaluate the wider suite. |
| CrowdStrike | Austin, TX, USA | Endpoint detection and response | Public platform vendor | Built its business on a cloud-delivered endpoint agent rather than on-premise infrastructure. Commonly the incumbent when a security team talks about replacing legacy antivirus. |
| Fortinet | Sunnyvale, CA, USA | Network security and SD-WAN | Public platform vendor | Sells a wide hardware and software portfolio anchored on its firewall line, with unusually deep reach into mid-market and distributed branch environments. Strong channel presence shapes how deals get sourced. |
| Check Point Software | Tel Aviv, Israel | Network and threat prevention | Public platform vendor | One of the longest-established firewall vendors, still widely deployed in large enterprises and government. Its installed base makes it a frequent displacement target for newer platforms. |
| Cisco Security | San Jose, CA, USA | Network security and observability | Division of a public company | Sells security as part of a much larger networking relationship, which often means the security decision sits with an infrastructure team rather than a standalone security buyer. |
| Trend Micro | Tokyo, Japan | Endpoint, cloud and server security | Public platform vendor | Long-standing presence across Asia Pacific and in server and workload protection specifically. Frequently found in hybrid estates that still run significant on-premise infrastructure. |
| Sophos | Abingdon, UK | Endpoint security and MDR | Private, sponsor-backed | Focuses on mid-market organisations that need enterprise-grade protection without an enterprise security team. Its managed detection and response service is now central to the offer. |
| SentinelOne | Mountain View, CA, USA | Endpoint and autonomous response | Public platform vendor | Competes directly with the larger endpoint platforms on automated detection and rollback. Often shortlisted alongside CrowdStrike in the same evaluation. |
| Zscaler | San Jose, CA, USA | Zero trust and secure access | Public platform vendor | Routes traffic through its own cloud rather than through appliances in a data center, which makes it a common choice during network modernisation projects. Deals frequently involve networking and security jointly. |
| Proofpoint | Sunnyvale, CA, USA | Email security and data loss prevention | Private, sponsor-backed | Concentrates on the human attack surface, meaning phishing, business email compromise and insider risk. Usually bought by teams that have already been hit by an email-borne incident. |
| Okta | San Francisco, CA, USA | Identity and access management | Public platform vendor | Provides workforce and customer identity as a service, sitting between employees and every application they touch. Identity projects tend to pull in IT, security and application owners together. |
| Rapid7 | Boston, MA, USA | Vulnerability management and SecOps | Public platform vendor | Combines vulnerability management with detection and response tooling aimed at teams that are stretched thin. Popular with organisations building a first formal security programme. |
| Tenable | Columbia, MD, USA | Exposure and vulnerability management | Public platform vendor | Best known for scanning technology that has become a default in many compliance programmes. Its footprint often extends into operational technology environments. |
| Qualys | Foster City, CA, USA | Vulnerability management and compliance | Public platform vendor | Delivers scanning and compliance reporting from its own cloud platform, with a long history in regulated industries. Frequently renewed on the strength of audit reporting alone. |
| CyberArk | Petah Tikva, Israel | Privileged access management | Public platform vendor | Specialises in controlling the accounts that carry the most damage potential, which keeps it central to audit and insurance requirements. Deployments usually involve identity and infrastructure teams. |
| Mimecast | London, UK | Email security and archiving | Private, sponsor-backed | Pairs email threat protection with archiving and continuity, which appeals to organisations with retention obligations. Common in professional services and financial firms. |
| Imperva | San Mateo, CA, USA | Application and data security | Subsidiary of a public company | Protects web applications, APIs and databases rather than endpoints, so its buyer is often an application or data team. Now part of Thales following its 2023 acquisition. |
| Forcepoint | Austin, TX, USA | Data security and secure access | Private, sponsor-backed | Focuses on data protection and user behaviour, with a substantial government and defense practice. Public sector procurement cycles shape much of its business. |
| Trellix | Milpitas, CA, USA | Extended detection and response | Private, sponsor-backed | Formed in 2022 by combining McAfee Enterprise with FireEye, so its installed base spans both heritages. Sells an XDR platform aimed at consolidating fragmented tooling. |
| Netskope | Santa Clara, CA, USA | Cloud security and SASE | Private, venture-backed | Built around visibility into cloud application usage, which extends naturally into secure access and data protection. Often evaluated when shadow IT becomes a board-level concern. |
| Darktrace | Cambridge, UK | Network detection and response | Private, sponsor-backed | Applies behavioural modelling to network traffic to flag activity that signature-based tools miss. Strong presence across Europe and in organisations without large analyst teams. |
| Arctic Wolf | Eden Prairie, MN, USA | Managed detection and response | Private, venture-backed | Sells security operations as a service to companies that will never staff a 24-hour SOC of their own. Its growth tracks mid-market demand for outsourced monitoring. |
| KnowBe4 | Clearwater, FL, USA | Security awareness training | Private, sponsor-backed | Runs phishing simulations and training programmes aimed at reducing human error rather than blocking traffic. Frequently bought by compliance and HR alongside security. |
| Ping Identity | Denver, CO, USA | Identity and access management | Private, sponsor-backed | Serves large enterprises with complex identity federation needs, and combined with ForgeRock in 2023 to broaden that footprint. Common in banking and healthcare estates. |
| BeyondTrust | Johns Creek, GA, USA | Privileged access and remote support | Private, sponsor-backed | Covers privileged access alongside secure remote support, which gives it a foothold in IT operations as well as security. Often adopted after an audit finding on admin accounts. |
| Secureworks | Atlanta, GA, USA | Managed detection and response | Subsidiary of a private company | Long-running managed security provider with deep incident response experience, acquired by Sophos in 2025. Its threat research output is widely cited across the industry. |
| Snyk | Boston, MA, USA | Application and developer security | Private, venture-backed | Targets developers rather than security teams, embedding scanning into the tools engineers already use. Deals often start bottom-up inside an engineering organisation. |
| Wiz | New York, NY, USA | Cloud security posture management | Private, venture-backed | Scans cloud environments without agents, which shortens the time between purchase and first useful finding. One of the fastest-adopted platforms in cloud-native organisations. |
| Cato Networks | Tel Aviv, Israel | SASE and network security | Private, venture-backed | Delivers networking and security as a single cloud service, appealing to companies tired of stitching appliances together. Popular with distributed mid-market businesses. |
| Barracuda Networks | Campbell, CA, USA | Email, network and data protection | Private, sponsor-backed | Serves small and mid-size organisations with bundled email, network and backup protection. Heavily channel-led, so partners often drive the buying conversation. |
We supply verified contacts at the companies above and at thousands of security vendors, MSSPs and consultancies this page does not list. Tell us the categories, regions and job titles you sell to and we will scope the match rate before you commit to anything.
A cybersecurity companies email list is a verified contact database of organizations that build, resell or deliver security products and services, together with the named decision makers inside them who approve and influence purchases. It is built for outreach rather than for research, so the value sits in the contact detail, not in the company profile.
A list that works has to do three things a scraped spreadsheet cannot. It has to say what kind of security company each record is, because an identity vendor and an OT security firm have almost nothing in common commercially. It has to name professionals by function, since security, IT, compliance and procurement all sit in the same buying decision but respond to completely different arguments. And it has to stay current, because this sector hires fast, gets acquired often, and rebrands more than most.
Our records carry the company, its primary security category, size and location, plus the contact name, title, department, seniority, a verified business email and a direct dial where one exists. That combination is what lets you write to a SOC manager about alert fatigue and to a compliance manager about audit evidence in the same account, without either message landing wrong.
Every record is built to be used the day it arrives, not cleaned for a week first.
Security vendors, MSSPs, MDR providers, consultancies and boutique specialists, each classified by primary security category.
Security leadership, technical architects, operations managers and the adjacent IT, compliance and procurement roles that shape purchases.
Revenue band, employee size, industry classification, SIC and NAICS codes, and full location down to ZIP code.
Business email, direct dial, mobile where available and compliant, plus a public LinkedIn profile URL.
Filter across all 14 tracked categories, from network and cloud security through to OT and industrial control system protection.
CSV or Excel, or a direct CRM push, with columns mapped before handover and a named contact if anything looks wrong.
Standard fields on every record. Tell us which ones you filter on and we will confirm fill rates before delivery.

Security purchases are rarely a single signature. These are the roles on the records, and what each one actually controls.
Signs off major security investment and owns board-level risk reporting.
In smaller vendors and startups, still personally involved in tooling decisions.
Often the technical half of a young security company, close to build versus buy calls.
Owns the IT budget that most security spending is drawn from.
Sets the technical architecture that security tooling has to fit into.
The central buyer for security platforms, services and staffing.
Runs the security function day to day and shapes the shortlist.
Controls infrastructure decisions that security products depend on.
Owns policy, controls and audit readiness across the estate.
Leads programme delivery and vendor evaluation.
Owns tooling used by analysts every day, so usability decides renewals.
Runs the detection and response team and its alert workflow.
Designs the reference architecture new products must slot into.
Owns security design across cloud platforms and landing zones.
Embeds security testing into build pipelines and developer workflow.
Controls the systems security tooling is deployed onto.
Owns firewalls, segmentation and secure connectivity.
Drives purchases tied to SOC 2, ISO 27001, HIPAA and PCI obligations.
Quantifies exposure and often holds influence over cyber insurance requirements.
Owns supplier onboarding, contract terms and negotiation.
Category is the single highest-impact filter on this data, because each segment buys and sells differently.
Firewalls, intrusion prevention, segmentation and secure gateways protecting traffic in and out of the estate.
Posture management, workload protection and configuration control across AWS, Azure and Google Cloud.
Detection and response on laptops, servers and mobile devices, replacing signature-only antivirus.
Single sign-on, multi-factor authentication, provisioning and privileged access control.
Code scanning, dependency analysis, API protection and web application firewalls.
Phishing and business email compromise defence, plus archiving and continuity.
Classification, encryption, data loss prevention and insider risk monitoring.
Feeds, research and enrichment that give context to alerts before analysts act on them.
Outsourced monitoring, triage and response for teams without a 24-hour SOC.
MSSPs running security tooling and operations on behalf of their clients.
Phishing simulation and training programmes aimed at reducing human error.
Scanning, prioritisation and remediation tracking across infrastructure and applications.
Architectures that verify every request rather than trusting anything inside the perimeter.
Protection for industrial control systems, manufacturing plant and critical infrastructure.
Security purchases are approved by named decision makers, not shared inboxes. Every record carries a person, a title and a verified email, so your message reaches someone who can act on it.
Filter to cloud security, endpoint, identity, MSSP or any of the other categories before you write. A message aimed at an identity vendor lands badly at an OT security firm.
Multiple contacts are matched to the same company across security, IT and procurement, which is what account-based programmes need to work.
Company size, revenue band, category and location are already on the record, so reps qualify from the file instead of rebuilding it in a browser.
Weekly re-verification and MX testing keep bounce rates low. In a sector this well connected, a burned sending domain is expensive to recover.
Conference and webinar campaigns live or die on timing. A current list beats a large one when the invitation has a date on it.
If your buyer works inside a security company, this is the list that reaches them.
Selling developer tools, analytics or infrastructure software into security vendors and their engineering teams.
Reaching security firms that resell, bundle or deploy hardware alongside their own products.
Targeting security companies choosing where to run their platforms and customer environments.
Offering implementation, audit readiness, virtual CISO or incident response support.
Running demand generation for clients that sell into the security market.
Filling seats at security conferences, roundtables and webinars with the right job titles.
Placing analysts, architects and security leadership, where hiring managers are the buyer.
Selling complementary tooling, or building channel and technology partnerships.
Recruiting resellers and MSSP partners into a channel programme.
Records are built from authoritative public sources and confirmed by analysts. Nothing is scraped from the open web or bought from a broker and resold as ours.
Every record runs through a rolling weekly re-verification cycle, and each address is MX-tested against a live mail server before delivery.
Anything that bounces inside the refresh window is credited back one for one, so you never pay twice for the same seat.
Category, region, seniority and company size filters are applied before delivery, so nobody on your team spends a week cleaning the file.
If a segment is thin we say so before you buy. A smaller accurate list beats a padded one that quietly damages your domain.
