§ Subcategory FAQ

The questions buyers ask before shortlisting.

Answered against the same disclosed methodology that powers every ranking on this page.

§FAQ.01

What is ABA Penetration Testing?

Penetration Testing is a service-vendor subcategory inside the IT / security services group on ABA Rank. ABA Rank indexes 23 firms that operate in penetration testing and ranks each on the same disclosed 100-point Index used across the rest of the services directory - qualified public reviews, profile completeness, and primary-category fit, with no paid tier among the inputs.

§FAQ.02

How does ABA Rank rank penetration testing firms?

Every firm in the Penetration Testing subcategory is scored on the same 100-point Index used across the rest of ABA Rank: 60 points from qualified public reviews, 35 points from profile completeness (the disclosed inputs specific to penetration testing), and 5 points from primary-category fit. As of methodology v3.0 no paid product contributes any Index points, and sponsored placements render in labeled slots above the ranked list rather than mixing into it. Methodology is fully disclosed at /how-we-rank.

§FAQ.03

Which penetration testing firm ranks #1 on ABA Rank today?

The current #1 in Penetration Testing is the top entry on this page; rankings refresh every night so the leader can change between visits. ABA Rank does not endorse a single permanent winner - the public Index recomputes from its three disclosed inputs (qualified public reviews, profile completeness, and primary-category fit) on a nightly cadence, and any firm that improves its disclosed inputs can move up.

§FAQ.04

How many penetration testing firms are listed on ABA Rank?

23 firms are currently ranked under Penetration Testing on ABA Rank. The directory is an editorial index of operating U.S. ABA firms; defunct or out-of-market entries are removed.

§FAQ.05

What does Verified mean for penetration testing firm on ABA Rank?

Verified means the listing subscribes to ABA Rank Verified, a review of the listing itself: that the firm controls it (proven with a work email at its own domain, its published phone number or its Google Business Profile), that its website answers over HTTPS, and that the profile is substantially complete, with any listed NPI checked against the federal NPPES registry. Software runs every check it can confirm and a reviewer handles the rest; the profile shows the date the review passed, or that it is still in progress. Verified service vendors carry a seal; unverified vendors remain ranked but are clearly marked. Verification is not a paid ranking boost.

§FAQ.06

How much do penetration testing firms cost?

Penetration Testing pricing varies widely by service line. ABA Rank publishes each vendor’s disclosed pricing model and pricing band on its profile when provided - there is no paid placement and no hidden referral commission. For deeper procurement work, /post-a-project routes a brief to three to seven matched vendors with disclosed pricing comparable side by side.

§FAQ.07

How does ABA Rank decide which firms qualify for Penetration Testing?

Subcategory assignment is editorial, not self-selected. The ABA Rank editorial team reviews each firm’s public website, primary service lines, and (where applicable) credential records, then assigns the most specific subcategory that matches what the firm actually does. Firms that span multiple subcategories appear in each one rather than being forced into a single bucket.

§FAQ.08

How can a firm get listed in Penetration Testing?

Any owner or authorized representative of an eligible firm can claim a free listing. Claimed profiles unlock the editable fields that drive the Index, and Verified ($490/yr) and Sponsor ($1,490/yr) tiers are optional paid upgrades disclosed in the methodology. New firms that are not yet on ABA Rank can be submitted at /suggest-vendor; submissions are reviewed weekly and approved listings typically appear within seven to ten days.
