What is the best single sign-on (sso) for small businesses?

The "best" single sign-on (SSO) solution for a small business isn't a one-size-fits-all answer, as it depends heavily on your existing tech stack, budget, number of users, and specific security needs.

However, I can highlight some top contenders and key factors to consider to help you make an informed decision.

**Key Factors for Small Businesses When Choosing SSO:**

1. **Existing Ecosystem:** Are you primarily a Microsoft 365 shop or a Google Workspace shop? This often dictates the easiest path.

2. **Ease of Setup & Management:** Small businesses often have limited IT resources, so a user-friendly interface and straightforward setup are crucial.

3. **Cost:** Budget is always a concern. Look for free tiers, affordable per-user pricing, or bundled solutions.

4. **Integrations:** Does it connect seamlessly with the cloud apps you already use (e.g., Salesforce, QuickBooks, Slack, Zoom, HR platforms)?

5. **Security Features:** Multi-Factor Authentication (MFA) is non-negotiable. Look for robust security policies.

6. **Identity Provider (IdP) Functionality:** Does it also manage user identities, or just provide SSO? Many small businesses benefit from a combined solution.

7. **Scalability:** Can it grow with your business?

**Top SSO Solutions for Small Businesses:**

Here are the leading options, categorized by common scenarios:

### 1. If You're Already a Microsoft 365 User: **Microsoft Entra ID (formerly Azure Active Directory)**

* **Pros:**

* **Likely Already Included:** If you have Microsoft 365 Business Standard or Premium, you already have access to Entra ID Free or Premium P1, respectively.

* **Seamless Integration:** Works perfectly with all Microsoft services (Teams, SharePoint, Outlook, etc.).

* **Robust Security:** Excellent MFA, conditional access policies (with Premium P1).

* **Extensive App Gallery:** Integrates with thousands of third-party SaaS apps.

* **Device Management:** Can integrate with Intune for device management.

* **Cons:**

* Can become complex for advanced configurations.

* Premium features (like advanced conditional access) require higher-tier M365 subscriptions or separate Entra ID licenses.

* **Best For:** Businesses heavily invested in the Microsoft ecosystem, looking for a unified identity and access management solution.

### 2. If You're Already a Google Workspace User: **Google Workspace (as an IdP)**

* **Pros:**

* **Less Robust Features:** May lack some of the advanced security and policy features of dedicated SSO solutions.

* **Best For:** Small businesses primarily using Google Workspace and a limited number of other SaaS applications, prioritizing simplicity and cost.

### 3. For a Modern, Cloud-Native, All-in-One Solution (especially with mixed OS environments): **JumpCloud**

### 4. Dedicated SSO Leaders (Scalable & Feature-Rich): **Okta & OneLogin**

* **Okta (Workforce Identity Cloud - Essentials/Express)**

* **Pros:** Industry leader, vast app catalog, highly reliable, excellent security features, very scalable.

* **Cons:** Can be pricier than other options, might offer more features than a very small business initially needs.

* **Pros:**

* **Affordable:** Often very cost-effective, especially for smaller teams.

* **Combines Password Management:** Provides secure password storage alongside basic SSO.

* **Easy to Start:** Simple to deploy and use for basic SSO needs.

* **Cons:**

* **Best For:** Very small businesses or those just starting their SSO journey, prioritizing budget and ease of use, and who also need a robust password manager.
