The fastest defensible improvement is to remove password-only access, then make every access request, endpoint, software change and recovery path visible and controlled. In practice, that means deploying phishing-resistant multifactor authentication (MFA), enforcing least-privilege zero-trust access, adding centrally managed endpoint detection and response (EDR), running continuous asset and vulnerability management, and testing isolated backups before an incident forces you to rely on them.
1. Replace password-only access with phishing-resistant MFA
Passwords can be stolen, reused or entered into convincing phishing pages. CISA recommends phishing-resistant MFA for every service, with priority on email, VPNs and accounts that reach critical systems. A concrete implementation is a FIDO2/WebAuthn security key, while passwordless sign-in can also use a device PIN, fingerprint or facial recognition combined with a cryptographic authenticator.
Start with the accounts attackers value most
- List administrator, domain, cloud-console, email, VPN and remote-access accounts.
- Require phishing-resistant MFA for those accounts before expanding to the rest of the organization.
- Map each service to an identity provider and confirm that its MFA policy actually accepts the chosen authenticator.
- Record who owns enrollment, how a lost device is replaced and which recovery methods are permitted.
Recovery planning is part of the control. Keep at least one documented, protected recovery route so a legitimate user is not locked out, but do not let help-desk resets quietly become a password-only bypass.
What to compare
- Phishing resistance: Prefer cryptographic, origin-bound authentication over methods that can be entered into a spoofed site.
- Coverage: Check support for administrators, employees, contractors, service accounts and every external-facing application.
- Device and account lifecycle: Define enrollment, replacement, suspension and offboarding ownership.
- Identity-provider integration: Test sign-in, recovery and policy enforcement in the systems you actually operate.
If you are evaluating hardware, “FIDO2 security key” is the useful product category to search. Verify operating-system, browser and identity-provider compatibility before buying.

2. Enforce zero-trust and least-privilege access
Zero trust means each request receives an authorization decision based on the user or workload identity, device state, requested resource and current risk. A network location is not treated as proof that access is safe. Least privilege then limits the permissions granted to only what the identity needs for the task and time required.
Apply the model where excessive access is most dangerous
- Privileged accounts: Separate administrative identities from ordinary user accounts, reduce standing privilege and require stronger approval for sensitive actions.
- Service accounts: Assign an owner, document the systems and data each account reaches, remove unused permissions and rotate credentials through a controlled process.
- Remote access: Make identity, device posture and resource sensitivity part of the decision instead of allowing broad network entry.
- Sensitive data: Segment access by application, dataset and operation, not just by office network or VPN membership.
NIST SP 1800-35, published June 10, 2025, documents 19 example zero-trust implementations developed with 24 collaborators across on-premises, cloud, hybrid-workforce and partner-access scenarios. Use those architectures as implementation patterns, not as an endorsement of a particular vendor.

Measure whether privilege is actually shrinking
Track the number of users and workloads with standing administrator rights, unmanaged accounts, broad network paths and access that lacks a current owner. A zero-trust project that adds a policy console but leaves those measures unchanged has not achieved least privilege.
3. Add endpoint prevention, detection and response
Endpoint protection should do more than report that antivirus is installed. Centrally managed EDR records behavior, raises alerts for suspicious activity and gives responders actions for triage and containment. Where the operating environment allows it, application allowlisting restricts execution to authorized software.

Compare EDR products and services on operations
| Dimension | Questions to answer |
|---|---|
| Visibility | Which processes, scripts, connections, identities and file changes are recorded? |
| Response | Can authorized responders isolate a device, stop a process, quarantine a file or collect evidence? |
| Platform coverage | Are the organization’s laptops, servers, cloud workloads and other critical assets supported? |
| Alert quality | How are duplicate, low-confidence and high-severity alerts prioritized? |
| Retention | How long is telemetry available, and can it be exported for an investigation? |
| Staffing | Who performs triage outside business hours and who has authority to contain an asset? |
EDR is a capability, not a guarantee that compromise will be prevented. Its value depends on coverage, usable telemetry and a response process that people rehearse.
4. Make asset, software, patch and vulnerability management continuous
You cannot protect systems you cannot identify. Maintain an authoritative inventory of hardware, software, accounts, data stores and dependencies, and mark which assets support revenue, safety or essential services.

Run the management loop
- Discover: Reconcile device, cloud, software, account and dependency data with an accountable owner.
- Prioritize: Combine technical exposure with business impact, internet exposure, exploitability and the importance of the service.
- Remediate: Patch, remove, reconfigure or isolate the highest-risk exposure first, while maintaining a documented exception path.
- Verify: Rescan or otherwise confirm that the fix took effect and that the vulnerable component is no longer reachable.
- Expire exceptions: Give every accepted risk an owner, compensating control and deadline.
CISA’s federal guidance distinguishes an urgent vulnerability-response playbook from the broader vulnerability-management program. A playbook helps coordinate a fast response to a critical issue; it does not replace continuous discovery, prioritization, remediation and verification.
Secure configuration belongs in the same process
Standardize hardened configurations for operating systems, browsers, cloud services and network devices, then detect drift. Inventory data should show not only what exists, but also whether it is patched, supported, securely configured and connected to a critical dependency.

5. Design recovery before the incident
Backups are useful only when attackers cannot alter every copy and the organization can restore the systems it actually needs. CISA advises: “Maintain offline, encrypted backups of critical data, and regularly test the availability and integrity of backups in a disaster recovery scenario.”
Make the backup system harder to compromise
- Keep at least one offline or otherwise isolated copy of critical data.
- Encrypt backup data and protect the encryption keys separately from ordinary administrator credentials.
- Use strong authentication and least privilege for backup administration.
- Document recovery priorities, dependencies and the people authorized to approve restoration.
- Retain golden images or infrastructure-as-code templates where rebuilding a clean platform is faster and safer than repairing a damaged one.
Prove that restoration works
Schedule restore exercises, record what was recovered, measure the elapsed time and correct failures. Test both individual files and complete services, including identity, networking, databases and application dependencies. NIST security measure SM 2.5 calls for backing up data, exercising restoration and being prepared to recover organization-essential software and platforms from backups at any time.
Prepare the ransomware handoff
- Use EDR and other monitoring to identify affected accounts, hosts and workloads.
- Move from detection to containment under a preassigned incident-response authority.
- Preserve the evidence and decisions needed for legal, regulatory, insurer and customer communications.
- Restore in the documented business-priority order from verified clean copies.
- Record the cause, control gaps and recovery results, then update access, endpoint and backup procedures.
An “offline encrypted backup drive” can support this process, but the drive alone is not a recovery strategy; rotation, key control, access restrictions and successful restore tests are required.
How to compare security-stack options
| Control | Comparison criteria | Evidence to request |
|---|---|---|
| Phishing-resistant MFA | Phishing resistance, service and device coverage, recovery workflow, identity-provider support | Successful enrollment and recovery tests for administrator and ordinary-user accounts |
| Zero trust | Policy granularity, identity and device integration, segmentation, user impact, cloud and on-premises reach | Reports showing reduced standing privilege and unmanaged access |
| EDR | Visibility, response actions, platform coverage, alert quality, retention and staffing requirements | Sensor coverage, sample investigations and documented containment authority |
| Backup and recovery | Offline isolation, encryption-key control, recovery-point and recovery-time objectives, restore-test evidence and cost | Dated restore reports for critical files and complete services |
| Managed services | Response coverage, escalation times, analyst expertise, retention, geography and contract scope | Written service boundaries, escalation contacts and after-hours procedures |
A practical rollout order
- Inventory critical services, privileged identities, external access paths, endpoints and backup dependencies.
- Require phishing-resistant MFA for administrators, email, VPN and critical-system access, with tested recovery ownership.
- Remove unnecessary standing privilege and narrow service-account and remote-access permissions.
- Deploy EDR or an appropriate managed service across critical assets, then connect alert triage to containment procedures.
- Run continuous vulnerability discovery, prioritization, remediation and verification, with expiring exceptions.
- Isolate and encrypt backups, protect their administration, and perform a documented restoration exercise.
- Exercise the full path from detection through containment, communications and recovery; use the findings to revise policies and ownership.
No single product prevents every compromise. The strongest security stack is the one that covers the accounts, assets and data that matter, gives responders usable evidence and authority, and demonstrates through testing that the organization can recover.
