GRSee vs Coalfire: SOC 2 Auditors

Choosing between GRSee and Coalfire for a SOC 2 audit usually comes down to company size and how hands-on you want the audit team to be. GRSee is a boutique, Israel-based cybersecurity and compliance firm founded in 2009, serving mostly seed-stage through mid-market SaaS companies. Coalfire is a much larger, US-based cybersecurity advisory firm with its own CPA affiliate, serving mid-market and enterprise clients across regulated industries including healthcare and government. Buyers researching GRSee vs Coalfire are typically comparing a smaller, high-touch boutique against a larger firm with broader framework coverage, not two firms competing for the exact same client profile. For a wider shortlist beyond these two firms, see the SOC 2 Auditors Directory.

GRSee

GRSee Consulting was founded in 2009 by co-founders Ben Ben Aderet and Iftach Shapira, starting with PCI DSS compliance work before expanding into SOC 2, ISO 27001, and other frameworks, according to GRSee's own about page. The firm's homepage states it is "trusted by 300+ SaaS, and high-growth companies" (grsee.com), consistent with its directory focus on Seed, SMB, and Mid-market companies. GRSee's own SOC 2 service page states plainly that an independent CPA issues the final report while GRSee coordinates the engagement and testing around it (grsee.com/services/soc2/), the same separation between readiness work and CPA attestation that applies across this category. GRSee also says it is "among the first accredited providers" for ISO 42001, the AI management system standard, on its dedicated ISO 42001 service page (grsee.com/services/iso-42001/), a differentiator for companies that need AI governance work alongside SOC 2.

Coalfire

Coalfire is a much larger cybersecurity advisory firm, reporting "1,000+ expert team members" and "1,000+ enterprise-forward clients across all major industries" on its company story page (coalfire.com/about/our-story). Coalfire's homepage states it performs "coordinated & comprehensive assessments across 85+ frameworks" (coalfire.com), a broader compliance footprint than a SOC 2-focused boutique typically carries. Coalfire's SOC assessment services page states that Coalfire Controls, its fully licensed and accredited CPA affiliate, performs SOC 1, SOC 2, SOC 3, and SOC for Cybersecurity engagements (coalfire.com/soc-assessment-services), so the firm issues its own report through an in-house CPA affiliate rather than coordinating with an outside CPA the way GRSee does.

What Is a SOC 2 Audit Firm Comparison

A SOC 2 audit firm comparison lines up two or more licensed CPA firms side by side on the dimensions that actually affect fit, such as the industries and company sizes each firm typically serves, the platforms its team already works inside, and where each firm is headquartered, rather than ranking the firms against each other. GRSee and Coalfire sit at different points on nearly every one of those dimensions: GRSee is a boutique, Israel-based firm serving mostly seed-stage through mid-market SaaS companies through a single confirmed platform partnership, while Coalfire is a much larger, US-based firm with its own CPA affiliate serving mid-market and enterprise clients across regulated industries including healthcare and government. Neither firm is objectively better than the other; the right choice depends on which firm's size, industry focus, and platform experience match the company being audited. A comparison like this one is meant to narrow a shortlist, not replace a direct conversation with each firm about scope, pricing, and timeline before signing an engagement letter.

GRSee vs Coalfire FAQs

Is GRSee or Coalfire the better SOC 2 auditor?

Neither is better in general. GRSee tends to fit smaller SaaS companies better, while Coalfire tends to fit mid-market and enterprise companies in regulated industries.

Does Coalfire's larger size mean a longer audit timeline?

Not necessarily, though Coalfire's directory record lists a 6 to 9 month timeline for a full advisory-plus-audit engagement, longer than a typical boutique SOC 2 engagement.

Can GRSee audit a company outside SaaS or technology?

GRSee's directory record lists SaaS, Technology, and Financial Services as its primary industries, so a company well outside those industries should confirm fit directly with the firm.

Does either firm issue the SOC 2 report through its own CPA?

Coalfire does, through its licensed CPA affiliate, Coalfire Controls. GRSee coordinates the engagement while a separate, independent CPA issues the report.

Which platforms does each firm already work with?

GRSee's directory record lists Secureframe as a confirmed platform partner, while Coalfire's lists Drata and Vanta.
