Cybersecurity newsletter sponsorships can put your brand in front of professionals evaluating security tools, cloud infrastructure, developer workflows, threat prevention, compliance, and risk-management products.
For B2B security marketers, the best placement is rarely the largest general-tech newsletter. Start with a publication whose audience already works in security, cloud operations, infrastructure, engineering, or adjacent technical roles. You can also browse the SlotFee directory to compare sponsor-ready B2B newsletters across more technical audiences.
How we selected these cybersecurity newsletters
This shortlist focuses on active SlotFee publications that serve security practitioners, cloud-security teams, technical developers, and infrastructure-focused readers. Each publication has a dedicated SlotFee profile with current listing details and a direct route to sponsorship information.
Prioritize audience relevance before reach. A focused audience of security and infrastructure professionals can be a stronger fit for a cybersecurity campaign than a much larger general technology audience.
Featured cybersecurity newsletters
Packt SecPro
Packt SecPro is a practical placement to consider for security-software brands looking to reach technical professionals. Its focus makes it relevant for campaigns involving application security, cloud security, infrastructure protection, DevSecOps, training, and security tooling.
Packt Attack & Defend
Packt Attack & Defend is an especially relevant option for brands connected to offensive security, defensive operations, threat detection, incident response, ethical hacking, and hands-on cybersecurity practice.
Infosec Weekly
Infosec Weekly is a direct fit for campaigns that need visibility with information-security professionals. It is worth evaluating for security platforms, identity tools, vulnerability-management products, compliance solutions, cyber-insurance services, and security-focused B2B software.
Cloud Security Guy
Cloud Security Guy reaches an audience at the intersection of cloud infrastructure and security. It is a strong option for cloud-security posture management, identity and access management, DevSecOps, monitoring, compliance, and infrastructure-protection campaigns.
HackerNoon Newsletter
HackerNoon Newsletter can provide broader technical reach among developers and technology professionals. It is most useful as a complementary placement when the campaign needs developer awareness alongside a more specialized security audience.
What to compare before you sponsor
Cybersecurity audiences are rarely interchangeable. Compare these details before choosing a placement:
Reader role: Confirm whether the publication reaches CISOs, security engineers, DevSecOps teams, cloud architects, developers, IT leaders, or a broader technology audience.
Security focus: Match the sponsorship to your category: identity, cloud security, application security, compliance, vulnerability management, threat detection, security education, or incident response.
Placement format: Ask whether the advertiser receives a dedicated feature, primary newsletter placement, mid-email slot, classified placement, or another sponsor format.
Audience data: Review available subscriber, reader, geographic, role, and engagement information. Use current publisher-provided figures for planning rather than assumed performance benchmarks.
Commercial terms: Confirm the live rate, package structure, lead time, creative specifications, tracking options, and cancellation policy before booking.
If your product also serves cloud-infrastructure and platform teams, see DevOps Newsletters to Sponsor. For a broader developer and engineering audience, compare Software Engineering Newsletters to Sponsor.
