What is SaaS Security Posture Management, SSPM Capabilities and Buyer’s Guide
Why SSPM matters right now
SaaS Security Posture Management, abbreviated as SSPM, is the practice and tooling that continuously checks the security configuration of software as a service applications, then guides or automates fixes. Modern teams run on Google Workspace, Microsoft 365, Slack, Salesforce, Atlassian, GitHub, ServiceNow and more. Each app exposes hundreds of switches that affect identity, data sharing, external access and auditability. SSPM turns this surface into observable controls, measurable risk and repeatable remediation.
SSPM is not only a product category. It is a way to operate. You define the controls that must hold across your portfolio, you monitor them for drift, and you correct drift quickly. The result is fewer accidental exposures, fewer over privileged identities, and better evidence for audits.
SSPM vs CSPM vs CASB
Before you evaluate tools, align on scope. The table below summarizes the typical boundaries.
| Area | SSPM, SaaS Security Posture Management | CSPM, Cloud Security Posture Management | CASB, Cloud Access Security Broker |
|---|---|---|---|
| Primary focus | Configuration and security posture inside SaaS tenants | Configuration and posture of cloud infrastructure like AWS, Azure, GCP | Visibility and control over cloud app usage and data paths |
| Typical objects | Tenants, org wide settings, roles, groups, sharing policies, OAuth apps, tokens | Cloud accounts, services, network, storage, identity, policies | Traffic, users, devices, data classification, session controls |
| Outcomes | Hardened settings, least privilege, safe sharing, audit evidence | Hardened infrastructure, reduced misconfig risk | Controlled access, data protection inline, anomaly response |
| Deployment | Vendor APIs and connectors | IaC scanning, APIs, agents where needed | Proxies, agents, APIs |
| Overlap | Identity hygiene, audit events, alerts and tickets | Some identity and logging | Data protection, anomaly detection, access policies |
CSPM hardens the foundation that engineers run. CASB governs access and data movement across cloud apps. SSPM dives deep into the switches inside each SaaS platform. Many security teams use all three, with clear swimlanes and shared findings.
Core SSPM control areas you must cover
A strong SSPM program tracks controls across four families. When acronyms appear, the first mention expands the term, then the acronym follows.
Identity and access hygiene in SaaS
Identity risk often hides in plain sight.
- Multi factor authentication adoption, including enforcement for admins and privileged roles
- Single sign on coverage for human and service accounts
- Role hygiene with least privilege reviews for admins and app owners
- Dormant, orphaned and duplicate accounts, including shared mailboxes and external guests
- Joiner, mover, leaver flows, with timely removal of access for departures
- Role based access control, abbreviated as RBAC, and break glass accounts with additional safeguards
Expected outputs include a baseline report, a list of high risk identities, and a schedule to reduce toxic combinations of permissions. Track mean time to remediate, abbreviated as MTTR, to measure improvement.
Third party OAuth and extension risk
OAuth permissions let external apps read and write data inside your tenants. The right apps improve productivity. Over scoped apps create incidents.
- Inventory of all authorized apps, extensions and bots across users and workspaces
- Scope analysis that flags sensitive grants like read all mail or full drive access
- Risk scoring based on publisher trust, scope sensitivity and user reach
- Allowlist and denylist policies with clear exception workflows
- Automated revocation for unused, over scoped or publisher removed apps
Your SSPM should show which OAuth apps touch sensitive stores like mail, drive, calendars, channels and records. It should also provide guided or automated revocation with user communication.
Data exposure and external sharing controls
Most SaaS risk comes from simple settings. A link that should be internal is public. A guest user has more access than intended.
- Public link discovery and cleanup for files, folders, sites and records
- External sharing policies by domain, group and sensitivity label
- Guest access governance, including idle guest removal and time bound invites
- Channel and site governance in collaboration suites, including shared channels and cross tenant sites
- File and message retention aligned to legal and business requirements
- Data loss prevention hooks, abbreviated as DLP, for content inspection where your stack supports it
Aim for measurable reductions in public links, unknown external domains and idle guests. Keep a recurring review that holds the line after cleanup finishes.
Auditability and evidence
Security posture is only valuable if you can prove it.
- Event capture across admin actions and critical configuration changes
- Evidence exports that summarize current state, exceptions and remediation proof
- Saved reports that can be reproduced on demand with clear timestamps
Plan for repeatable audits. Your SSPM should produce the same report on demand with immutable evidence.
Building a SaaS security management program
Technology is not enough. You need ownership, cadences and measures.
RACI, who owns what across security, IT and app owners
RACI stands for Responsible, Accountable, Consulted and Informed. Use it to assign decisions and actions.
- Security is accountable for policy and risk acceptance
- IT or platform teams are responsible for configuration and change execution
- App owners are consulted on business impact, exceptions and timelines
- Legal and privacy are informed, and sometimes consulted, for controls with regulatory impact
Write this model once, then reuse it across all apps. Keep it short, so people actually read it.
KPIs and OKRs for posture improvement
Measure outcomes, not just activity. Define key performance indicators, abbreviated as KPIs, and objectives and key results, abbreviated as OKRs.
- Percentage of users covered by multi factor authentication
- Percentage of admins reviewed for least privilege each quarter
- Number of public links reduced per month, then held steady
- Number of high risk OAuth apps revoked, and the total risk score over time
- Mean time to remediate misconfigurations, segmented by severity
- Percentage of critical SaaS apps with current evidence and owner sign off
Set realistic targets. Track trends, not single points.
SSPM buyer’s checklist and evaluation criteria
Use this section to evaluate platforms without brand bias. Focus on coverage, depth and time to value.
Integration depth across major platforms
Coverage claims are easy. Depth is what reduces risk. Use a grid like the one below during vendor calls.
| Platform | Depth signals to verify | Evidence to request |
|---|---|---|
| Google Workspace | Drive link policies, external domain allowlists, inactive accounts, admin role reviews, OAuth scope checks, retention settings | Sample findings, sample remediation, report template |
| Microsoft 365 | SharePoint and OneDrive public links, guest access controls, conditional access alignment, privileged identity checks | Before and after posture snapshot |
| Slack | Shared channels, external connections, file retention, app directory enforcement, workspace admin checks | Bulk fix demo in a sandbox |
| Salesforce | Profile and permission set sprawl, guest user access, API tokens, sharing rules, audit trails | Findings with remediation proof |
| Atlassian | Project and space permissions, public repositories in Bitbucket, access to secrets, admin group hygiene | Ticket integration example with rollback |
| ServiceNow and others | Scoped app risks, integration accounts, audit settings, data export controls | Evidence export with timestamps |
Push for specifics. Ask to see the exact switch the tool checks, the rule that flags drift, and the path to fix at scale.
Automation and remediation workflows
Automation saves time, but safety matters.
- Safe change previews that show impact before execution
- Bulk fixes with guardrails, including staged rollouts and rollback paths
- Ticketing integration with Jira, ServiceNow or your system of record
- Human in the loop approvals for high risk changes
- Notifications to affected users when access or sharing changes
Your SSPM should let you choose the right level of automation. Start with guided fixes. Move to automated actions for repeatable, well understood changes.
Control coverage checklist
Use this table as your program backbone.
| Control family | Example checks |
|---|---|
| Identity and access | Enforce multi factor authentication for admins, remove dormant accounts after defined time, least privilege for app owners |
| OAuth and third party apps | Deny high risk scopes by default, revoke unused apps after defined time, maintain allowlist for sensitive data access |
| Data sharing and exposure | Block public links by default, restrict external domains, expire guest access, align retention to legal holds |
| Audit and evidence | Log admin actions, archive configuration changes, export evidence on a schedule |
