What is an LLM vulnerability scanner?

An LLM vulnerability scanner sends batteries of adversarial probes — jailbreaks, prompt injections, PII extraction attempts, harmful-content requests — at a target LLM and grades the responses. The output is a vulnerability + optimization report with per-probe evidence, severity, and a prioritized fix list.

Which LLMs can I scan with FilterPrompt?

OpenAI, Anthropic, Google Gemini, Azure OpenAI, plus any OpenAI-compatible endpoint — Ollama, Groq, Mistral, Together AI, OpenRouter, Perplexity, Hugging Face, vLLM, or your own custom endpoint. Bring your own keys per tenant.

What kinds of vulnerabilities does FilterPrompt test for?

Jailbreaks (DAN, role hijack, translation smuggling), direct and indirect prompt injection, system-prompt extraction, harmful-content compliance, PII / secret leakage, bias & fairness, RAG poisoning, agent/tool abuse, output quality, and robustness — categories map to the OWASP LLM Top 10.

How are probes graded?

Each probe declares an evaluator: regex match, refusal-check, contains-check, or an AI judge (Gemini 3 Flash). Pass/fail comes with severity, category, the exact prompt sent, the model's full response, and the evaluator's reason — fully auditable.

How much does a scan cost?

1 credit per probe executed. New accounts get 1 welcome credit on signup. Pay-as-you-go credit packs after that — credits never expire. Connecting LLMs and creating tenants is free.

Enterprise Cybersecurity Buyer's Guide 2026

Complete enterprise cyber security buyer's guide for 2026. How to evaluate top cyber security companies, build the stack, and budget across categories.

Enterprise cyber security procurement is a multi-million-dollar, multi-year program decision. The wrong stack creates years of integration debt; the right stack reduces analyst burnout and measurably lowers breach risk. This 2026 buyer's guide covers how to think about enterprise cyber security as a portfolio, how to evaluate the top cyber security companies, and how to budget across the categories that matter.

The cybersecurity portfolio mental model

A modern enterprise cybersecurity program covers ten control categories: identity, endpoint, network, cloud posture, cloud workload, application, data, email, SaaS, and AI. No single vendor wins all ten, and consolidation pressure (the desire for fewer vendors) must be balanced against best-of-breed pressure (the need for credible coverage in each category). The right portfolio in 2026 is typically 8–15 vendors, with two or three platform anchors (e.g. CrowdStrike for endpoint/identity, Wiz for cloud, Microsoft for email/SaaS) and specialist tools filling the gaps.

Top cyber security companies by category

Identity — Okta, Microsoft Entra, Ping Identity, CyberArk (privileged access)
Endpoint — CrowdStrike, SentinelOne, Microsoft Defender
Network — Palo Alto Networks, Fortinet, Cisco, Check Point
SASE — Zscaler, Cloudflare, Netskope, Palo Alto Prisma Access
Cloud posture (CSPM) — Wiz, Palo Alto Prisma Cloud, Microsoft Defender for Cloud
Cloud workload (CWPP) — Sysdig, Aqua Security, Wiz Runtime
Application security — Snyk, Veracode, Checkmarx, Semgrep
Data security — Microsoft Purview, Skyflow, Imperva, Forcepoint
Email — Microsoft Defender for Office 365, Material Security, Abnormal, Proofpoint
SaaS security — AppOmni, Obsidian Security, Adaptive Shield
AI application security — FilterPrompt, Lakera, Robust Intelligence

Stack archetypes

Microsoft-anchored

Defender for Endpoint + Defender for Cloud + Sentinel SIEM + Purview DLP + Entra ID + Defender for Office 365. Add Wiz for multi-cloud, CrowdStrike or SentinelOne if Defender's endpoint quality is insufficient, and FilterPrompt for AI application security. Strongest if you are an E5 customer.

CrowdStrike-anchored

Falcon Insight (EDR) + Falcon Cloud Security + Falcon Identity + Falcon LogScale (SIEM) + Falcon Complete (MDR). Add Cloudflare or Zscaler for network edge, Wiz for deeper cloud posture, Snyk for app sec, Material Security for email.

Palo Alto-anchored

Strata firewalls + Prisma Access (SASE) + Prisma Cloud (CSPM/CWPP) + Cortex XDR + XSIAM. Heavy investment, deep integration, expensive consolidation play.

Best-of-breed

Okta (identity) + CrowdStrike (endpoint) + Cloudflare (network/SASE) + Wiz (cloud) + Snyk (app sec) + Material (email) + AppOmni (SaaS) + FilterPrompt (AI). Higher integration cost, better category-by-category capability, more flexibility on switching.

Evaluation framework for top cyber security companies

Score each candidate against your top-10 use cases (1–5 scale)
Weight cost (TCO over 36 months, not 12), integration depth, vendor stability, and roadmap fit
Require a paid POC against production-like data before any commitment over $100K ARR
Validate references in your industry and at your scale — 2 minimum
Negotiate renewal escalators (target ≤7%) and an off-ramp clause for material vendor changes

Budgeting

Defensible enterprise cyber security spend benchmarks for 2026: 8–12% of total IT spend in regulated industries (financial services, healthcare, defence), 5–8% in standard industries (SaaS, retail, manufacturing). For a 5,000-employee enterprise this is typically $8M–$25M annual security spend across tools, services, and headcount. The ratio of tools-to-services-to-headcount is roughly 35/25/40 for mature programs.

Common procurement mistakes

Consolidating onto one platform without independent evaluation — vendor pressure usually wins these decisions and quality suffers
Buying SIEM ingestion without modelling 36-month log volume growth — Splunk and Sentinel costs can exceed the platform fee
Skipping the paid POC because the vendor offered a free one — vendors run free POCs to control the test conditions
Treating compliance certifications (SOC 2, ISO 27001) as substitutes for technical capability assessments
Ignoring the AI application security category until after a customer-facing AI feature ships

AI as a 2026 procurement consideration

Two angles. First, AI features in the security tools themselves — most top cyber security companies now ship AI capabilities and the gap to non-AI competitors is widening. Second, AI features in your business — every enterprise shipping AI-powered functionality now needs an AI application security vendor. Treat the second as a new control category, not as an extension of an existing one. The category leaders (FilterPrompt, Lakera, Robust Intelligence, HiddenLayer) are specialist; the major platform vendors do not yet cover this layer credibly.

Operational considerations

Tool selection is half the work. The other half is operating model: who owns each tool, who triages alerts, who tunes detections, who handles incidents, and how vendor relationships are managed. A typical enterprise cybersecurity program has 12–25 FTE in security operations, plus contracted MDR or MXDR for after-hours coverage. Without the operating model, the best stack still under-delivers.

FAQ

How many cybersecurity vendors should an enterprise have?

8–15 is typical and defensible. Below 8 usually means coverage gaps; above 20 means integration debt.

Should we move to a single platform vendor?

Rarely the right answer. Even Microsoft, Palo Alto, and CrowdStrike have meaningful gaps that require complementary tools. Consolidation is a directional goal, not an absolute one.

How often should we re-evaluate the stack?

Major review every 3 years; tactical reviews of underperforming tools annually. Avoid rip-and-replace cycles shorter than 3 years — switching cost is real.

Conclusion

Enterprise cyber security is a portfolio decision across ten control categories, with a target of 8–15 vendors weighted to your stack archetype and threat model. The top cyber security companies in 2026 are well known; the harder skill is building the operating model around them and adding the new categories (cloud posture, SaaS security, AI application security) as the threat surface expands.
