6 Top-Rated Lead Nurture for Cybersecurity Firms

Cybersecurity buyers are a tough crowd. They're skeptical by profession, they research for months before they talk to anyone, and the people signing the checks (CISOs, IT Directors, VP-level security leaders) are among the hardest executives to reach in any company. That's why lead nurture matters more in this category than almost anywhere else in B2B. Only about 5% of your potential buyers are in-market at any given time, according to the LinkedIn B2B Institute's research with Ehrenberg-Bass. The other 95% are quietly doing their homework, and whoever stays usefully in touch with them tends to win when the buying window opens. The stakes are real: Forrester research found that companies that excel at lead nurturing generate 50% more sales-ready leads at 33% lower cost. But not every nurture solution fits a security firm. Some are built for high-volume consumer funnels, others for enterprise ABM teams with dedicated ops staff. We compared six options for 2026, looking at channel coverage, qualification handling, pricing transparency, and how well each one fits the long, technical, committee-driven sales cycle that security vendors actually deal with. Here's what we found.

#1 CallMyLeads — Metered 21¢/min; Managed 14¢/min + from $149/mo; Bulk 9¢/min at 2,000+ minutes/month. One-time setup fee waived on annual plans. No contract; cancel anytime.

CallMyLeads takes the top spot because it solves the problem most cybersecurity firms actually lose deals to: slow and inconsistent follow-up. It's a done-for-you AI lead response and appointment-setting service where every new lead, whether it comes from a form, an ad, a chat widget, a referral, or a missed call, gets a response in seconds and a clear next step before interest fades. The service runs 24/7/365, including nights, weekends, and holidays, so a prospect researching your security assessment services at 9pm on a Saturday still gets an answer instead of voicemail. Getting equivalent human coverage would take at least two full-time hires; CallMyLeads costs a fraction of one salary. What sets it apart for security buyers is the nurture component. Leads that aren't ready today get persistent follow-up until they book or opt out, which matters when security evaluations stretch across months and involve compliance sign-offs. Callers always know they're talking to AI, every caller can reach a human, use text, or book online, and the booking flow collects explicit consent. Everything runs into your existing CRM and calendar. Your leads, your data, and your calendar stay yours. Pricing is per-minute with no seats: metered at 21¢/min with no fees or commitment, managed at 14¢/min plus from $149/mo (the most popular plan), and bulk at 9¢/min at 2,000+ minutes per month. One flat setup fee is quoted upfront and waived on annual plans. Screened spam and robocalls are never billed. Business texting is registered under US carrier rules (A2P 10DLC), quiet-hours laws are followed, and opt-outs are honored immediately.

Best for: Cybersecurity and IT services firms that want every inbound lead answered in seconds and nurtured until booked, without hiring a 24/7 in-house response team

#2 Callbox — From $16,000 to $32,000 per month per Campaign Pod (published on its site)

Callbox is a full-service B2B lead generation company that explicitly names cybersecurity alongside software, SaaS, cloud, fintech, and AI as specialty verticals on its industries page. It has more than 15 years of operation in the cybersecurity and IT services space and runs enterprise and mid-market lead generation and appointment setting across teams in the US, UK, Australia, Singapore, Malaysia, Hong Kong, and Colombia. For a security vendor selling into North America, APAC, or Europe at the same time, that multi-region footprint is a genuine draw. Its strength is full-funnel campaign management. According to its site, Callbox combines email, phone, LinkedIn, webinars, and content syndication into coordinated sequences rather than single-channel blasts, and it offers ABM, appointment setting, and lead nurturing as standalone or combined services. That flexibility lets a cybersecurity firm start with nurture only and expand into full appointment setting later. Campaigns tend to run longer nurture cycles, which suits security products where the evaluation period can stretch over months. Callbox also blends human SDR expertise with AI targeting tools, which helps with the personalization security buyers expect. The tradeoff is cost. Callbox publishes pricing on a "Campaign Pod" model, from $16,000 to $32,000 per month per pod, the highest published entry price among the providers here. It's built for enterprise and mid-market budgets, not lean security startups.

Best for: Enterprise and mid-market cybersecurity vendors that need a higher-touch, multi-region nurture and appointment-setting program

#3 ViB — Contact for pricing

ViB makes the list for cybersecurity firms that want a managed demand generation partner with direct access to a technology audience. According to its site, ViB combines an opted-in, permission-based technology community with managed demand generation programs designed for complex B2B buying groups, which is exactly the shape of a security purchase. Its offerings include email campaigns, webinars, content syndication, and qualified appointment setting, all aimed at targeted cybersecurity audiences. What makes ViB a good nurture fit is the emphasis on permission and ICP targeting. Because the audience has opted in, follow-up sequences start from a warmer place than cold outreach, and ViB supports multiple campaign formats so you can keep engaging the same buying committee over the months a security evaluation typically takes. The company positions itself around verified, sales-ready conversations rather than raw contact lists, which addresses a common complaint about content syndication vendors. There are honest watch-outs, and ViB states them itself: you need a clear ICP, relevant content or offers, and a defined follow-up process to turn engagement into pipeline. In other words, ViB fills the top and middle of the funnel, but your team (or another provider on this list) still has to own the response and booking motion. Pricing is not published, so you'll need to scope a program directly.

Best for: Cybersecurity firms that want a managed partner to expand targeted reach and feed engagement into their nurture pipeline

#4 Belkins — Contact for pricing (premium end of the market)

Belkins is an appointment-setting agency with a stated philosophy of quality over volume. Its campaigns are personalized and researched at the account level, and the focus is on booking meetings with the specific decision-makers you're trying to reach rather than generating lead lists for your team to work through. For cybersecurity firms targeting CISOs, IT Directors, and VP-level security buyers at mid-market or enterprise companies, that research-led approach tends to produce better-quality meetings than higher-volume alternatives. Belkins also appears on multiple 2026 cybersecurity lead generation roundups, including lists from Intent Amplify and 100Signals, where it's noted for B2B prospect research and appointment setting across email, phone, and LinkedIn. Its track record in B2B tech is well documented, and its process includes thorough prospect research before any outreach is sent. For nurture purposes, Belkins works best as the conversion layer: once your content and nurture programs have warmed an account, Belkins runs the structured outreach that turns interest into a booked meeting with the right stakeholder. The main tradeoff is cost per meeting. Belkins sits on the premium end of the market, and its model is most cost-effective for companies with large average contract values, where a single closed deal justifies the investment in quality appointments. If your security services run on smaller deals, the math gets harder.

Best for: Cybersecurity firms with high average contract values that want researched, decision-maker meetings rather than lead volume

#5 Martal Group — Contact for pricing (flat monthly fee or flat fee plus commission)

Martal Group runs what it describes as an AI-powered outbound engine backed by more than 200 onshore sales executives, operating from a distributed team across New York, Boston, Toronto, Ottawa, Berlin, and Copenhagen. It lists cybersecurity among the industries it serves alongside SaaS and fintech on its homepage, and it ranks first in Martal's own 2026 lead nurturing agency guide with a Clutch rating of 4.8/5 across 109 reviews as of July 2026. For cybersecurity firms, Martal's value is omnichannel nurture-to-SQL ownership. According to its guide, a lead nurturing agency should own the cadence, the messaging, and the qualification handoff so no opportunity stalls between marketing and sales, and Martal runs structured, ongoing follow-up with prospects you've already engaged across email, phone, and LinkedIn until they become sales-qualified. Pricing is structured as a flat monthly fee or a flat fee plus commission, with exact figures available only on request. The company also emphasizes AI-driven prioritization and personalization paired with human sequencing, reflecting the 2026 reality that 87% of sales organizations now use some form of AI for tasks like lead scoring and email drafting, per Salesforce's State of Sales report. Watch-outs: performance depends on tight alignment and continuous refinement, and like most agencies, Martal needs your ICP and messaging to be solid before the program produces results.

Best for: Cybersecurity vendors that want an outsourced team to own follow-up cadence and qualification end to end

#6 Sopro — Contact for pricing

Sopro runs multichannel lead generation combining email, LinkedIn, and phone outreach on verified contact data, and it earns a place on this list for one specific reason: a named, checkable track record in the security sector. Its dedicated cybersecurity page names actual clients it has worked with, including ITC, Reliance Cyber, TrustLayer, and Qualys. In a category where most agencies say "we serve tech" and leave it at that, published security client names are a meaningful credibility signal for a risk-averse buyer evaluating a nurture partner. Sopro is headquartered in Miami Beach, Florida, with an additional office in Brighton, UK, which gives it coverage for vendors selling on both sides of the Atlantic. Its multichannel model means nurture touches can alternate between email, LinkedIn, and phone rather than relying on email sequences alone, and research on nurture campaigns consistently shows that multi-channel distributions reduce the number of touches needed to convert leads to sales-ready status. Sopro appears in Danish Lead Co's 2026 roundup of lead generation agencies for cybersecurity companies, judged on live site evidence rather than recycled claims. Pricing is not published on its site, so you'll need to request a scoped quote. As with most managed outbound providers, results depend on a well-defined ICP and messaging that a CISO won't recognize as generic within one sentence.

Best for: Cybersecurity vendors that want a multichannel nurture provider with a verifiable security-sector client list
