Security posture management continuously monitors and improves your organization's security configurations across all systems. Over 90% of successful cyberattacks begin with phishing, yet most programs focus on cloud infrastructure rather than the platforms where attacks actually originate: email and communication systems.

• Continuous monitoring surpasses periodic audits by detecting configuration drift in real time across cloud and email environments.

• Email and communication platforms represent a critical gap in most security posture management programs.

• Behavioral AI transforms posture management by correlating configuration settings with actual user behavior patterns.

• Extending CSPM with SaaS-focused posture management closes the visibility gap that attackers exploit most frequently.

Security posture management is the continuous monitoring, assessment, and improvement of an organization's security status across systems, applications, and configurations to reduce risk before attackers exploit weaknesses. According to NIST, security posture is "the security status of an enterprise's networks, information, and systems based on information security resources and capabilities in place to manage the defense of the enterprise."

Unlike periodic assessments, effective security posture management operates continuously, identifying gaps, tracking configuration changes, and providing actionable guidance to reduce risk. Six major compliance frameworks mandate continuous monitoring rather than annual assessments: FedRAMP, HIPAA (2024 proposed rule), CMMC, FFIEC/BSA and SOC 2.

Security posture management prevents the misconfigurations that drive the majority of modern breaches, addressing risks that periodic manual audits miss. Security teams relying on periodic manual audits miss configuration drift between reviews, while rapid cloud adoption has expanded the attack surface dramatically.

Effective security posture management programs combine five essential capabilities that work together to prevent misconfigurations from becoming breaches.

Complete visibility into all systems forms the foundation of posture management. CIS Control 1.1 requires organizations to maintain an accurate, up-to-date inventory of all enterprise assets through automated discovery tools, encompassing end-user devices, cloud services, SaaS applications, and email platform configurations.

Establishing security baselines creates the measuring stick against which configurations are evaluated. CIS Benchmarks provide prescriptive guidance for platforms including Microsoft 365 email security and Google Workspace email security, specifying recommended settings for authentication, access controls, data sharing, and audit logging.

Programs continuously monitor for configuration changes that deviate from established baselines. Real-time drift detection alerts security teams when changes occur, enabling evaluation before misconfigurations persist undetected for months. Traditional audits capture a snapshot on a specific day, yet configuration changes happen daily in cloud environments and email platforms. Continuous monitoring detects and evaluates changes immediately, surfacing configuration drift as it occurs.

Programs should provide actionable guidance aligned with risk-based prioritization. A missing MFA requirement on a global administrator account represents far greater risk than a slightly permissive file sharing setting. Using frameworks like CISA's SSVC methodology, security teams receive evidence-based guidance on which issues demand immediate attention and which can wait for scheduled maintenance. This prevents email alert fatigue and accelerates remediation of critical exposures.

Automation addresses common misconfigurations immediately rather than waiting for manual review cycles. Organizations extensively using AI and automation can significantly reduce breach costs compared to those relying on manual processes, while freeing security teams for higher-value work. Solutions that automate SOC operations enable teams to focus on strategic initiatives rather than routine configuration reviews.

Email platform misconfigurations enable the majority of successful cyberattacks, yet most organizations monitor only infrastructure security posture. Many organizations implement Cloud Security Posture Management (CSPM) for infrastructure while failing to deploy SaaS Security Posture Management (SSPM) for Microsoft 365 and Google Workspace.

CSPM tools monitor only the infrastructure organizations deploy and manage directly within cloud accounts—compute instances, storage buckets, and network configurations. They cannot see into third-party SaaS applications like Microsoft 365 and Google Workspace, precisely where over 90% of cyberattacks originate.

This creates a critical blind spot: organizations achieve visibility into resources that rarely serve as initial attack vectors while leaving email platforms—the primary entry point for breaches—completely unmonitored.

Platforms like Microsoft 365 and Google Workspace contain numerous configuration options affecting security. Common misconfigurations create specific attack pathways:

• Disabled MFA requirements on administrator accounts

• Legacy authentication protocols that bypass MFA entirely

• Missing email authentication records (SPF, DKIM, DMARC)

• Malicious mail flow rules created by compromised accounts

• Overly permissive OAuth application access grants

Missing DMARC email authentication policies allow convincing phishing emails appearing to come from your domain. Enabled legacy authentication lets attackers bypass MFA. Permissive OAuth grants provide persistent access without credentials.

Email misconfigurations enable account takeover, credential-based persistence, and data exfiltration through predictable attack progressions:

1. An attacker sends a phishing email attack that evades detection due to missing authentication enforcement

2. An employee enters credentials on a fake login page through credential phishing

3. The attacker accesses the account through legacy protocols bypassing MFA

4. They create forwarding rules for visibility into sensitive communications

5. They begin reconnaissance for financial fraud or data theft, often leading to vendor email compromise

Each step involves a preventable misconfiguration that continuous posture management would detect.

Behavioral AI extends security posture management beyond checking settings to understanding how configurations interact with actual user behavior and communication patterns. Static configuration checking answers whether something is configured correctly. Behavioral AI expands this by answering whether configurations are being used correctly.

Abnormal's behavioral AI operates through a three-layer framework that provides comprehensive security context:

• Identity Awareness establishes baselines for individual users, understanding their typical communication patterns, login behaviors, and role-based activities across the organization

• Context Awareness analyzes relationships between users, vendors, and applications to identify anomalies that deviate from established patterns of normal interaction

• Risk Awareness correlates signals across all layers to assess the true threat level of configuration changes and user activities in real time

A mail forwarding rule might comply with policies yet represent a security incident if created by a compromised account. By analyzing how configurations interact with actual behavior patterns, Abnormal's Behavioral AI identifies situations where technically compliant settings create elevated risk. An email account with properly configured permissions becomes high-risk when combined with unusual login locations, mass file downloads, and recently created forwarding rules.

Abnormal's interconnected knowledge bases continuously analyze Microsoft 365 configurations against behavioral baselines:

• PeopleBase tracks individual user behavior patterns and communication norms

• VendorBase monitors external partner interactions and identifies supply chain risks

• AppBase catalogs third-party application permissions and OAuth grant patterns

• TenantBase maintains organization-wide configuration baselines and security policies

Together, these knowledge bases detect when technically compliant settings create elevated risk through correlation with user behavior patterns. This approach identifies security gaps that static configuration audits miss, providing continuous visibility into posture drift without requiring manual review cycles.

Effective security posture management requires extending visibility beyond infrastructure to email and communication systems. Abnormal enhances existing security programs by providing continuous security posture management for Microsoft 365 environments, complementing infrastructure-focused CSPM tools. The platform automatically detects misconfigurations, monitors for drift, and provides prioritized remediation guidance.

Abnormal automatically compares email platform settings against CIS Benchmarks, identifying gaps where configurations fall short of industry-standard security baselines. This enables organizations to demonstrate compliance while ensuring their Microsoft 365 and Google Workspace environments meet established security standards.

Combined with inbound email security capabilities, organizations gain comprehensive protection that addresses both configuration weaknesses and active threats targeting their email environment.
