Top 7 Cybersecurity B2B Marketing Agencies for 2025: Global Experts Driving Growth

Cybersecurity has become one of the most competitive and high-stakes industries in the world. With threats evolving daily and CISOs under constant pressure, cybersecurity vendors face a unique marketing challenge: standing out in a saturated market that often looks the same – think hoodies, shields, and binary code clichés.

Breaking through requires more than running ads or writing blog posts. It demands specialized B2B marketing expertise that blends creativity, credibility, and execution at scale. Whether your goal is to build brand awareness, generate qualified leads, or expand into new geographies, the right partner can make all the difference.

This article highlights the 7 best cybersecurity B2B marketing agencies in 2025, showing how each approaches the challenge differently.

Full-Stack vs. Specialist: Which Agency Do You Need?

Not every agency is designed for the same type of support. Here’s how to decide:

• Full-Stack Agencies act like an outsourced marketing department. They handle everything from strategy and messaging to content, campaigns, events, and automation. This is ideal if you’re a startup or scale-up without a large internal team – or if you want to expand globally and need end-to-end support.
  
• Specialist Agencies focus deeply on one domain, such as SEO, content, or PR. They’re best if you already have a strong in-house team but need targeted help filling expertise gaps.
  

* Pro tip: One of the most important criteria when evaluating an agency is their HubSpot Partner status. At minimum, choose an agency that is a HubSpot Diamond Partner- this ensures they not only know strategy and content, but can also build the automation and CRM backbone that powers scalable demand generation.

1. SAGE Marketing

Best for: Full-stack global growth + creative storytelling for CISOs

SAGE Marketing is a full-stack B2B marketing agency with a strong track record in cybersecurity. With offices in Israel and the United Kingdom, SAGE has helped more than 100 global tech companies sharpen positioning, scale demand generation, and build credibility with CISOs in both the U.S. and European markets.

What makes SAGE stand out is its ability to take complex, technical cybersecurity solutions and turn them into clear, memorable narratives — while also building the full infrastructure to convert those stories into pipeline. As a HubSpot Diamond Partner, SAGE ensures every marketing campaign is backed by world-class CRM, automation, and analytics.

Case Study: Salt Security – Creativity that Travels Across Borders

At RSA, one of the largest cybersecurity trade shows in the U.S., SAGE helped Salt Security run a campaign that was impossible to ignore. Instead of shields and hackers, they gave out unsalted popcorn with the message:
“You wouldn’t leave salt out of your popcorn, so why leave it out of your API security?”

The metaphor was simple, fun, and sticky. It created buzz on the show floor, cutting through the noise of hundreds of vendors. Later, SAGE adapted Salt’s campaigns for the European B2B market, localizing content and messaging for CISOs dealing with new API threats under different regulatory frameworks.

Case Study: Radiflow – Scaling OT Cybersecurity Marketing in the U.S. & Europe

Radiflow, an OT/ICS cybersecurity company protecting critical infrastructure, needed to reposition its brand and systematize growth. Their lead sources were fragmented and nurturing was almost non-existent.

SAGE built a HubSpot-powered marketing engine, introducing structured messaging, lead scoring, automation, and campaign orchestration.

The impact was measurable:

• 400% growth in new leads within the first year
• 150% increase in SQLs
• 300% boost in website traffic
  

This gave Radiflow a scalable growth engine that worked in both the U.S. critical infrastructure market and across European utilities and industrial buyers.

Why SAGE Stands Out

• Creativity that resonates with CISOs (Salt Security, U.S. + Europe)
• Systematic funnel building and automation (Radiflow, U.S. + Europe)
• Global reach with local expertise bridging Israel’s cyber innovation hub with North American and European buyers
• HubSpot Diamond Partner status ensuring CRM + automation infrastructure is world-class
  

Best fit: If you want a global full-stack partner to elevate your cybersecurity brand with both creativity and execution.

2. Powered by Search

Best for: Pipeline growth & performance marketing

Known for predictable growth frameworks, Powered by Search has worked with cybersecurity vendors like Fortra to maximize pipeline and optimize customer acquisition costs.

3. Concurate

Best for: Revenue-driving content marketing

Concurate focuses on content that generates inquiries and revenue rather than vanity metrics. Strong for cybersecurity firms needing thought leadership.

4. Bluetext

Best for: Branding & market positioning

A veteran in cybersecurity marketing, Bluetext is strong in rebrands, PR, and repositioning for vendors looking to break out of crowded niches.

5. Magnetude Consulting

Best for: Mid-to-large firms with complex needs

Award-winning and experienced in cybersecurity, Magnetude handles strategy + execution at scale, including ABM campaigns.

6. The Rubicon Agency

Best for: Strategic storytelling & differentiation

Known for transforming technical jargon into compelling narratives. A natural fit for EMEA-focused campaigns.

7. Bora

Best for: Cybersecurity content & advocacy

Focused on cybersecurity content at scale — whitepapers, case studies, thought leadership, and advocacy programs.

AI-Ready Marketing: The 2025 Differentiator

In 2025, the best agencies are also AI-ready. They integrate automation and predictive analytics to:

• Score and prioritize leads
• Personalize campaigns across geographies
• Automate repetitive workflows
• Forecast pipeline velocity
  

Frequently Asked Questions (FAQ)

What is the best B2B cybersecurity marketing agency in 2025?

The “best” depends on your needs. If you want a full-stack global partner, SAGE Marketing stands out with case studies in the U.S. and Europe. If you only need specialized support like branding or PR, agencies like Bluetext or Bora are strong choices.

How do I choose between a full-stack agency and a specialist?

Full-stack = all-in-one outsourced marketing team. Specialist = deep expertise in one area (SEO, content, PR).

Why is global/GEO experience important in cybersecurity marketing?

Cyber threats and buyers are global. Agencies with U.S. + Europe expertise (like SAGE) can adapt campaigns to regulations, culture, and buyer expectations.

What results should I expect from an agency?

Look for both creativity and measurable results. Example: Salt Security gained major RSA buzz; Radiflow saw 400% lead growth.
