Snowflake Security Review
Snowflake holds the data everyone in the business wants and the role hierarchy grew to match. We pen test what each role actually inherits, whether network policies apply, and whether a credential alone is enough to reach it. CREST-certified testers, fixed price from £3,280, scoped in 24 hours.
- Unlimited retesting
- No rescheduling or cancellation fees
- Fixed quote within 24 hours
“I would highly recommend EJN Labs to any organisation seeking reliable, detailed, and well-managed penetration testing services, particularly for government or enterprise-level projects.”
Imran SaghirProject Lead, SquareOne“There wasn’t another company we could find that could deliver what we needed in the timeframe we needed. The client loved it, and we got instant ROI from the engagement.”
Dan WilcocksonCo-Founder, CelloriThe lesson the industry took from 2024 was blunt: analytics platforms holding enormous datasets were reachable with a username and password alone, because multi-factor authentication and network policies were available but not enforced. Enforcement is the first thing we check.
Why a credential should not be enough
After that it is the role graph. Snowflake roles inherit, and a hierarchy built incrementally over several years frequently grants ACCOUNTADMIN or SECURITYADMIN further down than anyone intends. We enumerate the graph and test what each role can actually see rather than what the documentation claims.
Then the sharing surface. Secure data sharing, reader accounts and listings are powerful and easy to over-grant, and a share that exposes a table rather than a masked view hands out the raw data permanently.
ISO 27001, SOC 2, PCI DSS and Cyber Essentials Plus audits accept manual penetration test evidence. Scan-only evidence is generally insufficient.
ROLES, POLICIES + SHARES
What we actually pen test on a Snowflake account
Manual pen testing across role hierarchy and privilege inheritance, authentication and network policy, shares and data exchange, masking coverage and integration credentials.
Role hierarchy and privilege inheritance
The full role graph enumerated and tested, which roles inherit account-level privileges, ownership chains, future grants, and whether a standard analyst role can escalate through grant paths.
Authentication and network policy
Whether multi-factor authentication is enforced rather than available, key pair authentication usage, network policies and their coverage, and whether any user can authenticate with a password from anywhere.
Shares, reader accounts and listings
Every outbound share and listing enumerated for what it exposes, whether shared objects are masked views or raw tables, reader account configuration, and inbound shares and their trust.
Masking, row access and tagging
Dynamic data masking and row access policy coverage against the columns that need it, whether a privileged role bypasses masking, and tag-based policy application.
Integrations and external access
Storage integrations and their cloud credentials, external functions and the endpoints they call, external stages and what they can read or write, and Snowpipe configuration.
Logging, warehouses and cost abuse
Access history and login history retention, whether unusual queries would be detected, warehouse auto-suspend and resource monitor configuration, and whether a compromised account could run up significant cost unnoticed.
METHODOLOGY
Snowflake Security Review: From Scope to Attestation
CREST-aligned methodology built on OWASP Web Security Testing Guide, OWASP ASVS, NIST SP 800-115, and PTES. Each finding maps to all four standards plus your specific compliance regime.
Reconnaissance
Application mapping, technology fingerprinting, content discovery, parameter enumeration, authentication-flow analysis, role-matrix construction.
Vulnerability Assessment
Authenticated and unauthenticated automated scanning across every user role, plus targeted manual checks for known weakness patterns.
Manual Exploitation
Hands-on testing by a CREST-certified pentester. Business-logic exploitation, chained vulnerabilities, privilege escalation, impact validation.
Reporting + Retest
Executive summary, technical report with CVSS scores and reproduction steps, walkthrough call, free retest after remediation, attestation letter.
CREDENTIALS
Verified Accreditations Auditors Accept
Every credential below is independently verifiable. UK procurement teams, FCA supervisors, ISO 27001 / SOC 2 auditors, and cyber insurance underwriters all recognise these standards.

FAQ
Frequently Asked
Is this a penetration test or a configuration review?
Predominantly a configuration and privilege review, tested rather than read. We authenticate as the roles you provide and establish what each can actually reach, which is the question that matters for a data platform.
Will you run expensive queries?
No. We agree warehouse limits before starting and work with the smallest warehouse that will do, and we avoid full table scans on large datasets entirely. Cost is part of what we assess, not something we add to.
Do you need ACCOUNTADMIN?
No. A role with sufficient visibility to enumerate grants is useful, plus two or three ordinary roles to test boundaries between. We will tell you exactly what we need and why.
What about the data itself?
We do not extract it. Demonstrating that a role can read a table does not require reading the rows, and the report records the finding without reproducing any of your data.
What do we receive?
A report mapped to ISO 27001, SOC 2 and GDPR where personal data is in scope, a prioritised remediation plan, and unlimited free retesting.
