These three aren't direct competitors, but they're the closest of any trio in this set to genuinely complementary: holistic.dev catches SQL issues in source…
Contact for pricing
Best for: Development teams that want SQL source code reviewed for performance, security, and architecture problems without ever connecting a scanner to the live database.
Subscription · From $39/month (billed annually at $468/year)
Best for: Teams wanting one affordable dashboard that runs Nmap, OpenVAS, Nessus, OWASP ZAP, and Nuclei continuously against live websites, servers, networks, and APIs.
Contact for pricing
Best for: Large organizations that need active, production-grade defenses - WAF, bot protection, DDoS mitigation, API security, and data security - rather than just detection or scanning.

Three different layers of an app security pipeline
holistic.dev works pre-deployment on SQL source code, hostedscan.com works post-deployment by scanning live infrastructure, and Imperva works in production by actively blocking attacks. A mature security program could plausibly use all three at different stages rather than picking one.
holistic.dev, hostedscan.com, Imperva
hostedscan.com aggregates known open-source scanners instead of building proprietary detection
hostedscan.com's core value proposition is combining Nmap, OpenVAS, Nessus, OWASP ZAP, and Nuclei into a single dashboard for continuous scanning, rather than developing its own detection engine from scratch. That's a meaningfully different architecture from Imperva's proprietary enterprise WAF and data security stack.
hostedscan.com
Only Imperva actively blocks attacks
holistic.dev and hostedscan.com are both detection tools - they find problems in code or live infrastructure but don't stop an attack in progress. Imperva is the only one of the three offering active production defenses like a WAF, bot protection, and DDoS mitigation.
Imperva
A stark pricing accessibility gap
hostedscan.com publishes a clear, affordable price ($39/month, or $468/year billed annually), while both holistic.dev and Imperva are contact-for-pricing with no public numbers. That makes hostedscan.com the only one of the three a small team can realistically self-serve into without a sales conversation.

Not really. They operate at different stages of an application security lifecycle: holistic.dev analyzes SQL source code before it's deployed, hostedscan.com continuously scans already-deployed websites, servers, networks, and APIs for vulnerabilities, and Imperva actively defends production applications with a WAF, bot protection, and DDoS mitigation. A team could reasonably use all three together rather than choosing just one.
hostedscan.com, by a wide margin on transparency. It publishes a clear starting price of $39/month ($468/year billed annually). Both holistic.dev and Imperva are contact-for-pricing with no public numbers, which typically means a longer sales process before you know the cost.
No. holistic.dev explicitly analyzes SQL source code to flag performance, security, and architecture issues without ever connecting to the live database or its data. That's a meaningful distinction from hostedscan.com and Imperva, both of which interact with live, running systems.
hostedscan.com combines several established open-source security scanners - Nmap, OpenVAS, Nessus, OWASP ZAP, and Nuclei - into one unified dashboard for continuous scanning of websites, servers, networks, and APIs, rather than relying on a single proprietary engine.
Probably not as a starting point. Imperva is built for large, regulated organizations and is sold entirely through custom, contact-for-pricing sales, with no published self-serve plan. A smaller team is more likely to start with hostedscan.com for affordable vulnerability scanning and holistic.dev for SQL code review, then evaluate an enterprise-grade WAF like Imperva as they scale.
