How can organizations stop the top identity-related threats?

Identity risk is the leading vector for modern breaches; with 90% of organizations seeing identity incidents last year, prevention must be proactive and layered.

What are the most common identity-related threats today?

The top identity risks are Business Email Compromise (BEC), credential stuffing, account takeover (ATO), authentication bypass, and infostealer-driven breaches. Each vector exploits either human behavior, weak credentials, or misconfigured systems and can lead to financial loss, data theft, or broader network compromise. These threats often chain together: a leaked password enables credential stuffing, which can become an ATO and then a ransomware event. Modern defenses require controls at email, endpoint, identity, and cloud layers. MSPs and security teams need clear processes and continuous monitoring to stay ahead.

What is Business Email Compromise (BEC) and how do you stop it?

BEC is a targeted scam that impersonates trusted insiders to trick staff into transferring funds or revealing secrets; prevention centers on detection, training, and authentication. Run regular phishing simulations and give employees concrete reporting steps to reduce human risk. Apply email authentication standards—SPF, DKIM, and DMARC—to cut down on spoofed messages; check your setup with Palisade’s DMARC tool: Check your DMARC. Layer email filtering, strong approval workflows for financial requests, and visibility into unusual sender behavior.

How does credential stuffing work and what stops it?

Credential stuffing uses leaked passwords tested across many services to gain access; stop it by enforcing unique credentials, monitoring for reuse, and adding friction like MFA. Rotate and retire credentials regularly, and block logins from suspicious IPs or devices. Endpoint hygiene matters—infostealers that capture passwords and cookies are a common starting point—so keep endpoints patched and protected. Consider an MDR service for continuous detection and rapid containment.

What is account takeover (ATO) and how can it be prevented?

ATO happens when attackers gain control of a user account and act as that user; prevent it with least-privilege access, fast offboarding, and vigilant session management. Revoke unused permissions in cloud consoles and SaaS apps and enforce role-based access control. Monitor for anomalous logins, sudden permission changes, or unfamiliar API activity. An incident playbook that includes immediate credential resets and token revocation reduces damage when an ATO occurs.

How do attackers bypass authentication and what should you do?

Authentication bypass occurs when weak MFA, exposed credentials, or misconfigurations let attackers impersonate users; fix it by enforcing strong multi-factor authentication and hardening cloud configs. Remove or restrict overly-privileged service accounts and close public S3 or storage exposures. Use conditional access policies to require device compliance and location-based restrictions. Regular configuration audits and automated policy enforcement reduce the risk of simple missteps turning into breaches.

Why are infostealers a growing problem and how do you stop them?

Infostealers quietly harvest credentials, tokens, and cookies from infected endpoints and often feed credential-stuffing and ATO attacks; prevent them with endpoint protection and user-focused defenses. Use EDR/XDR tools to detect suspicious exfiltration and block malicious processes. Train users to avoid untrusted downloads and to recognize social-engineering lures. Pair endpoint controls with identity monitoring so stolen secrets can be detected in authentication logs.

How can MSPs protect client cloud environments from identity risk?

MSPs must enforce least privilege, segregate tenants, and automate permission checks across multi-tenant clouds to keep clients secure. Implement role separation for admins and use service accounts with narrow scopes and short-lived credentials. Apply automated scanning to find exposed buckets or over-permissioned roles. Document and enforce offboarding and third-party access termination to avoid lingering access after personnel changes.

What immediate steps should IT teams take this week?

Start with the basics: enforce MFA everywhere, run a permissions audit, and launch phishing simulations to gauge user readiness. Roll out conditional access policies and block legacy authentication where possible. Validate email authentication (SPF/DKIM/DMARC) — check DMARC with Palisade: Test DMARC — and schedule endpoint scans for infostealers. Finally, ensure you have an incident response plan and 24/7 detection capability, either in-house or via an MDR partner like Palisade.

What long-term controls reduce identity risk most effectively?

Long-term, combine strong identity governance, continuous monitoring, and automation: least privilege, just-in-time access, and identity-aware network controls are essential. Use identity analytics to spot risky behavior and automate remediation of stale permissions. Invest in MDR or SIEM integrations that correlate identity alerts across email, endpoint, and cloud. Regularly test your controls with red-team exercises and tabletop drills.

How does multi-factor authentication (MFA) help and are there limits?

MFA drastically lowers the chance of unauthorized access by requiring a second factor, but not all MFA is equal—prioritize phishing-resistant methods like FIDO2 or certificate-based tokens. OTP SMS or email codes are better than nothing but are vulnerable to SIM swap and interception. Enforce MFA for sensitive roles and make it mandatory for remote access. Combine MFA with session risk checks and device posture assessment for stronger protection.

What role do managed detection and response (MDR) services play?

MDR teams provide 24/7 monitoring, faster detection, and expert incident response, which is critical for catching identity-driven attacks early. An MDR can correlate authentication anomalies with endpoint alerts and network telemetry to stop attack chains. For MSPs, an MDR partner simplifies operations and scales coverage across clients. Look for MDR providers that integrate identity signals and offer rapid containment steps.

How should organizations measure identity security success?

Track metrics like number of credential reuse incidents blocked, MFA adoption rate, phishing simulation click rates, time-to-detect identity anomalies, and the count of stale permissions removed. Regularly test email authentication effectiveness with DMARC reports — use Palisade’s DMARC tool to verify settings: Analyze DMARC. Combine technical metrics with business-impact KPIs like prevented fraudulent transfers or avoided downtime.

FAQ

1. How fast should we respond to a suspected ATO?

Respond immediately: reset credentials, revoke active sessions and tokens, and review recent activity logs within the first hour to contain damage.

2. Is MFA enough to stop credential stuffing?

MFA is a strong defense but should be paired with monitoring, blocking suspicious IPs, and session protections to stop advanced bypass attempts.

3. Can small MSPs afford MDR?

Yes—MDR can be cost-efficient compared with breach costs; many providers offer scalable packages tailored to smaller MSPs and their clients.

4. What’s the quickest win to reduce email fraud?

Implement DMARC with quarantine or reject policies after monitoring, and train staff to verify payment requests via secondary channels.

5. How often should we run phishing simulations?

At least quarterly for general staff and monthly for high-risk roles; use results to target training where click rates remain high.
