SaaSFort Intruder charges $149/month for its cheapest plan. Detectify starts at €302/month for Surface Monitoring alone. If you’re a 20-person SaaS company trying to answer a prospect’s security questionnaire, that’s a hard line item to justify — especially when you need results today, not after a week-long onboarding.
SaaSFort starts at €9/month. Same category: external vulnerability scanning. Very different price tag.
This isn’t a hit piece. All three tools solve real problems. But they solve them for different teams, at different price points, with different trade-offs. Here’s the honest breakdown.
What Each Tool Actually Does
Intruder is a UK-based vulnerability scanner built for infrastructure teams. It combines OpenVAS, Nuclei, and Nessus scanning engines to test networks, cloud environments, and web applications. Intruder shines when you need to scan internal networks, track cloud asset sprawl across AWS/Azure/GCP, and manage large attack surfaces. Their target customer is a mid-market IT team with dozens of servers and cloud instances.
Detectify is a Swedish EASM (External Attack Surface Management) platform. Its core value is asset discovery — finding subdomains, APIs, and services you didn’t know existed. Detectify’s crowdsourced vulnerability research means they often catch novel attack vectors before other scanners. Their sweet spot is security teams at 200+ person companies who need to monitor a sprawling external surface.
SaaSFort is a German security scanner purpose-built for B2B SaaS companies selling to enterprise. It runs 60 checks across 21 categories in under 60 seconds and produces a procurement-ready Deal Report with an A–F grade. No infrastructure scanning, no agent installation — just point it at your domain and get results.

Pricing: The €140/Month Elephant in the Room
This is where the gap gets hard to ignore.
| Plan | SaaSFort | Intruder | Detectify |
|---|---|---|---|
| Entry price | €9/month | $149/month (~€137) | €302/month (Surface only) |
| Mid-tier | €19/month | $299/month (~€275) | €392/month (Surface + App) |
| Full tier | €29/month | $499/month (~€460) | Custom (typically €500+) |
| Annual savings | ~€86–€278/year | ~20% discount | Annual billing required |
| Free option | ✅ Unlimited free scans | 14-day trial | Request demo |
At the entry level, Intruder costs 15x more than SaaSFort. Detectify costs 33x more.
For a 15-person SaaS startup, $149/month means $1,788/year on vulnerability scanning — before you’ve closed your first enterprise deal. SaaSFort at €9/month is €108/year. That’s the difference between a rounding error and a budget conversation.
When the higher price makes sense
Intruder’s $149 plan includes infrastructure scanning with OpenVAS and Nuclei engines. If you’re running 50 servers across three cloud providers and need to scan internal networks, SaaSFort won’t cover that. Intruder will.
Detectify’s €302/month buys you continuous attack surface monitoring with crowdsourced vulnerability research. If you’re a 500-person company with hundreds of subdomains you’ve lost track of, that discovery capability has real value.
But if your need is “prove to enterprise buyers that our SaaS product is secure” — you don’t need infrastructure scanning or subdomain enumeration. You need a fast scan, a clear grade, and a report procurement can read.
Who Each Tool Is Built For
Choose Intruder if you:
- Manage internal networks alongside web applications
- Run workloads across multiple cloud providers (AWS, Azure, GCP)
- Need infrastructure vulnerability scanning (OpenVAS, Nessus)
- Have a dedicated security or DevOps team to interpret results
- Budget $1,800–$6,000/year for scanning
Choose Detectify if you:
- Have a large, sprawling external attack surface (100+ subdomains)
- Need crowdsourced, zero-day vulnerability research
- Want continuous asset discovery and monitoring
- Have a security team of 3+ people
- Budget $3,600–$10,000+/year
Choose SaaSFort if you:
- Sell B2B SaaS and face security questionnaires from enterprise buyers
- Need a procurement-ready security report you can send within minutes
- Want NIS2 and ISO 27001 compliance evidence without hiring a consultant
- Don’t have a dedicated security team (CTO handles security)
- Need results in under 60 seconds, not hours
- Budget under €350/year
Why SaaSFort Wins for SMBs
Three reasons this matters beyond price:
1. Time-to-value is measured in seconds, not days. Enter your domain at saasfort.com/scan, get your A–F grade and 60-check report before your coffee gets cold. No DNS verification, no agent installation, no onboarding call. Intruder’s setup takes 30–60 minutes minimum. Detectify requires DNS verification and a sales call for most plans.
2. Reports speak procurement’s language. SaaSFort’s Deal Report maps findings to OWASP Top 10, NIS2, and ISO 27001 frameworks — the exact references enterprise buyers look for in vendor assessments. Intruder and Detectify produce technical vulnerability reports designed for security engineers. If your buyer’s procurement team receives a raw CVE list, it creates more questions than answers.
3. The price gap funds your actual security work. The €4,000+/year you save versus Intruder or Detectify can pay for a proper annual pen test, a SOC 2 readiness assessment, or actual vulnerability remediation. Security budget should go to fixing problems, not to paying for a dashboard your team checks once a month.
What SaaSFort Doesn’t Do (And Why That’s Fine)
SaaSFort doesn’t scan internal networks. It doesn’t discover shadow IT assets across cloud providers. It doesn’t run authenticated application scanning with crawling and fuzzing.
If you need those capabilities, Intruder and Detectify are genuinely good tools.
But according to Verizon’s 2025 Data Breach Investigations Report, 68% of breaches involved a human element or basic security misconfiguration — exactly the type of issues external scanning catches. For most B2B SaaS companies under 200 employees, external scanning plus continuous monitoring covers the attack vectors that enterprise buyers actually ask about.
Frequently Asked Questions
Is SaaSFort a direct replacement for Intruder or Detectify?
Not exactly. SaaSFort replaces the external web scanning portion of what Intruder and Detectify do — which is often the only part SMBs actually use. If you need internal network scanning (Intruder) or large-scale attack surface discovery (Detectify), those tools cover capabilities SaaSFort intentionally skips. For B2B SaaS companies whose primary need is enterprise-ready security evidence, SaaSFort delivers that at a fraction of the cost.
Can I use SaaSFort alongside Intruder or Detectify?
Yes. Some teams use SaaSFort for instant Deal Reports and A–F grades when responding to security questionnaires, while keeping Intruder or Detectify for infrastructure monitoring. At €9/month, adding SaaSFort to an existing stack is trivial.
How does SaaSFort’s scan depth compare to Intruder’s multi-engine approach?
Intruder combines OpenVAS, Nuclei, and Nessus — three scanning engines that together cover infrastructure, network, and web vulnerabilities. SaaSFort runs 60 targeted checks across 21 categories focused specifically on what enterprise buyers evaluate: OWASP Top 10, SSL/TLS, security headers, DNS, and compliance framework alignment. Different depth, different purpose. For a deeper dive on what enterprise procurement actually evaluates, see our security evidence guide.
Does SaaSFort support NIS2 compliance reporting?
Yes. SaaSFort maps scan findings to NIS2 Article 21 requirements and generates compliance evidence automatically. Neither Intruder nor Detectify currently offer NIS2-specific compliance mapping — a gap that matters especially for German and EU-based SMBs facing the October 2026 deadline.
What if I outgrow SaaSFort?
SaaSFort’s Scale tier at €29/month covers the needs of most SaaS companies up to Series B. If you grow to 500+ employees with complex multi-cloud infrastructure, you’ll likely need a platform like Intruder or Detectify alongside SaaSFort — not instead of it. The Deal Report and procurement-ready grade remain valuable regardless of company size.
