Intruder.io alternatives grouped by need: scanners, AI pentests and hybrid platforms, with list prices, units, scope and retest terms checked 9 Nov 2026.

> **Short answer:** Intruder.io sells vulnerability scanning and an AI web app pentest at $3,500 per test. Alternatives fall into three groups: scanners (Detectify, Pentest-Tools.com), AI pentests (Aikido, Horizon3.ai NodeZero) and hybrid platforms with human testers (Astra Security, Cobalt). Price units differ: per test, per month, per year, per asset. Checked 9 November 2026.

Intruder.io alternatives depend on which Intruder product you use. Intruder.io (not the Burp Suite tool of the same name) sells vulnerability scanning and an AI web application pentest. If you want a scanner, look at Detectify and Pentest-Tools.com. If you want an AI pentest, look at Aikido and Horizon3.ai. If you want human testers, look at Astra Security and Cobalt. All facts below come from vendor pages checked on 9 November 2026.

## Why look for Intruder.io alternatives?

Buyers usually leave for one of four reasons. Intruder's AI pentest covers web applications, and its pages do not state API, cloud, network or mobile scope. Its two pricing pages disagree on price ($3,500 or $4,000 per test, see [Intruder pricing](/pricing/intruder/)). Its platform plans show no readable price. And its pages describe no human review of findings.

If one of those matters to you, the groups below show where to look.

## Which alternatives publish a price?

All six options publish at least one price. The units differ, so the table does not rank them.

| Provider | Group | Published price | Unit |
|---|---|---|---|
| Intruder (for reference) | Scanner and AI pentest | Single AI web app pentest $3,500; 4-pack $12,000; product page $4,000 | per test; per pack of 4 (about $3,000 each); per test, standalone |
| Aikido | AI pentest | TYPICAL Pentest $4,000; Rightsized Pentest $50 to $30,000+ | per assessment |
| Astra Security | Hybrid | Pentest Auto $2,999; Pentest Expert $5,999; Pentest Enterprise from $9,999; Scanner Lite $69 monthly or $699 annual | per year (Auto card also shows $199 per month); per target for Scanner Lite |
| Cobalt | Hybrid | Autonomous Pentest $3,500 (limited-time offer) | per test |
| Detectify | Scanner | Starter from EUR 0; Standard from EUR 2,500; Professional from EUR 5,000; Enterprise from EUR 15,000; PCI ASV Scanning EUR 500 | per year (annual platform fee) |
| Horizon3.ai (NodeZero) | AI pentest, network-first | Flex $15; Core $50; Pro $65; Elite $85; WebApp Flex $10,000 | per asset per test; per asset per year; per app per test |

## Which alternatives test web apps, APIs or networks?

Scope is recorded from vendor pages. "Unknown" means the pages checked do not state it.

| Provider | Web app | API | Cloud | Network | Mobile |
|---|---|---|---|---|---|
| Intruder | Yes | Unknown | Unknown | Unknown | Unknown |
| Aikido | Yes | Yes | Unknown | Yes | Yes |
| Astra Security | Yes | Yes | Yes | Yes | Yes |
| Cobalt | Yes | Yes | Yes | Yes | Yes |
| Detectify | Yes | Yes | Unknown | Unknown | Unknown |
| Horizon3.ai (NodeZero) | Yes | Yes | Yes | Yes | Unknown |
| Pentest-Tools.com | Yes | Yes | Yes | Yes | Unknown |

Detectify is the closest match if you want scanning of web apps and APIs. Horizon3.ai is the match if network and Active Directory testing matter most. For web-focused AI agents, see [XBOW alternatives](/compare/xbow-alternatives/).

## How do the options compare on retests and turnaround?

Retest terms and turnaround differ more than price. Intruder lists unlimited retesting on the single test and the 4-pack, with results within hours per its pricing page.

| Provider | Retest terms | Turnaround |
|---|---|---|
| Aikido | Free retesting for up to 6 months, including checks for bypasses of fixes | TYPICAL Pentest: results on the day (vendor claim); the AI pentest page also says a few hours, minutes, and in one place days |
| Astra Security | Re-scans included: Auto 1, Expert 2, Enterprise 4; window 30 days (Auto, Expert) or 90 days (Enterprise) | Manual pentest 10 to 15 working days; Pentest Auto first report on the day of the order (vendor claim) |
| Cobalt | Free retesting for 6 months (Standard) or 12 months (Premium, Enterprise) in the table; FAQ says unlimited during the contract term; the two statements differ | Autonomous Pentest findings in 24 hours; annual tiers start within 3, 2 or 1 business days |
| Detectify | Not stated on the pricing page | Not published |
| Horizon3.ai (NodeZero) | Fix actions with one-click verify; no extra charge on Core, Pro, Elite | Not published as a time |
| Pentest-Tools.com | Unlimited rescans on all paid plans (tool scans) | Not published |

## Is there a different answer for Detectify users?

Detectify is a scanner, so its users look for tools in the same group. In this list, that means Intruder, Pentest-Tools.com and Astra's Scanner Lite. Detectify lists web and API scope. The others add network or cloud scope, depending on the vendor. Detectify's pricing page does not state retest terms or a turnaround time, so ask for both when you compare.

## How should you test a shortlist?

Shortlist two options from different groups, then run the same checks on both.

1. Pick one real target and a written scope with the same assets for each vendor.
2. Seed it with two or three known issues, such as a missing authorization check in a staging copy. Do not use production.
3. Compare what each report proves: request and response evidence, not scanner banner text.
4. Check what a retest costs and how long it takes after you fix one issue.
5. Ask what a human reviews, and what the vendor does not test.

The [pentest vs vulnerability scan guide](/guides/pentest-vs-vulnerability-scan/) explains why a scanner result and a pentest report are different documents, and the [automated pentesting tools guide](/guides/automated-pentesting-tools/) covers the AI group.

## Questions

### Which Intruder.io alternative has the lowest published price?

Pentest-Tools.com lists a free plan ($0, up to 5 scanned assets per scan cycle) and paid plans from $96 per month. Detectify lists Starter from EUR 0 per year. These are scanning plans. Aikido lists a Rightsized Pentest from $50 per assessment, and the price rises with scope.

### Do any alternatives offer a human-led pentest?

Astra Security is hybrid: its manual pentest takes 10 to 15 working days. Cobalt is hybrid with annual tiers. Both list a price only for part of the range. Ask for the scope and the tester's role in writing.

No. Intruder.io is a vendor that sells vulnerability scanning and an AI web app pentest. Burp Intruder is a tool inside Burp Suite. Searches for either name return both.

### What are Detectify alternatives?

Intruder, Pentest-Tools.com and Astra's Scanner Lite sell scanning. Detectify lists web and API scope with annual fees from EUR 0 to EUR 15,000. Check each vendor's scope before you switch.
