Why teams compare

Why teams look at Bishop Fox alternatives

These are the reasons buyers most often give us when they compare providers. They are not a judgement of Bishop Fox's service.

One team, not a crowd

Some teams want the same testers each time, who already know their product.

A report for the auditor

Compliance-driven teams need a report their SOC 2, ISO 27001 or PCI DSS auditor accepts first time.

A different way to buy

Some prefer a fixed price per scope; others prefer credits or a subscription.

More than a pentest

Some want continuous code, app and attack surface testing between pentests, from the same provider.

The alternatives

Five Bishop Fox alternatives, in detail

We're ioSENTRIX, so we've put ourselves first. What we say about the others comes from their own websites, with sources at the bottom of the page.

Expert firmPTaaS subscription or creditsCTEM

ioSENTRIX

ioSENTRIX's own testers, never a crowd or freelancers, run scoped penetration tests on web, API, mobile, cloud, network, thick client, IoT and embedded, POS, ICS/OT and AI applications. Every fix is retested for free, the price is fixed unless the scope changes, and we work with your auditor until the report is accepted.

Between tests, continuous threat exposure management (CTEM) keeps watching: continuous SAST, DAST, SCA and SBOM, EASM and CAASM for your attack surface, and network security testing, all from the same team.

Buyer’s checklist

How to choose a penetration testing provider

Ask every provider on this page these eight questions, ioSENTRIX included.

01
Who will test, and will it be the same people next time?
A named team learns your product. A rotating group brings fresh eyes.
02
Is retesting included?
Ask how many rounds, and whether retests cost extra or use credits.
03
Will the report satisfy my auditor?
Name your framework (SOC 2, ISO 27001, PCI DSS, HIPAA) and ask for a sample report.
04
How is the price set, and what changes it?
Fixed per scope, credits or subscription: know what moves the number.
05
Can you test my specialist targets?
Thick clients, devices, POS, ICS/OT and AI features need specific skills.
06
What happens between pentests?
Ask whether code, apps and your attack surface are tested continuously.
07
What accreditations does the firm hold?
Look for company-level accreditation such as CREST, and ISO 27001.
08
How fast can testing start?
Ask for the first available date for your scope, not a general promise.
