Jamf Security Review
Jamf runs scripts as root on every Mac you manage. Anyone who can create a policy has root on the fleet, and the API roles that integrations use are frequently scoped to everything because scoping them properly took longer. CREST-certified testers, fixed price from £2,580, 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, CelloriA Jamf policy can execute a script as root on every enrolled Mac. That places the Jamf console alongside your most privileged systems, and the people who hold access to it alongside your most privileged administrators, which is not always how it is governed.
Why fleet management is root access
API roles are the second concern and usually the more exposed one. Integrations need credentials, those credentials get created with broad privilege because narrowing them is fiddly, and they end up in scripts, monitoring tools and occasionally source control.
Then coverage: whether configuration profiles enforcing FileVault, firewall, Gatekeeper and screen lock actually reach every device, and whether a Mac can be enrolled by someone who should not be able to enrol one.
ISO 27001, SOC 2, PCI DSS and Cyber Essentials Plus audits accept manual penetration test evidence. Scan-only evidence is generally insufficient.
POLICIES, ENROLMENT + API ROLES
What we actually pen test on a Jamf deployment
Manual pen testing across policy and script privilege, enrolment and device trust, configuration profile coverage, API role scope and Self Service exposure.
Policies, scripts and privilege
Who can create and scope policies, script content and the context it runs in, approval controls, whether a policy can be scoped to the whole fleet by a junior administrator, and Self Service policy exposure.
Enrolment and device trust
Enrolment methods permitted, whether user-initiated enrolment is open, Automated Device Enrolment configuration, whether enrolment can be bypassed or a device unenrolled locally, and supervision status.
Configuration profile coverage
Which devices fall outside the profiles enforcing FileVault, firewall, Gatekeeper, screen lock and software update, scoping gaps, and whether a user can remove a profile.
API roles and integrations
Every API role and client enumerated with its privilege, whether any exceeds what its integration requires, credential storage and rotation, and what a compromised API client could do to the fleet.
Console access and accounts
Administrator account privilege and multi-factor enforcement, single sign-on configuration, dormant accounts, and audit logging of console actions.
Inventory and extension attributes
What inventory collection gathers, whether extension attribute scripts leak sensitive data into inventory records, and who can read device and user records.
METHODOLOGY
Jamf 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
Do you test Jamf Pro, Jamf School or Jamf Now?
Primarily Jamf Pro, which is where the privilege and the complexity sit. Jamf School deployments in education we test on the same basis, adapted to the narrower feature set.
Will you push a policy to our Macs?
Only to a test device you nominate and only with written agreement. The privilege can usually be demonstrated without executing anything on real devices.
Do you need administrator access to the console?
Read-only visibility of policies, scopes and API roles is what the review needs. We also want an ordinary administrator account at the privilege level a help desk user would hold, to test what that can reach.
We use Intune for Windows and Jamf for Mac. Should we test both?
Usually yes, and the comparison is often the finding. Estates commonly enforce noticeably stronger policy on one platform than the other, and attackers go to whichever is weaker.
What do we receive?
A report mapped to Cyber Essentials, ISO 27001 and the CIS macOS benchmark where relevant, a prioritised remediation plan, and unlimited free retesting.
