Implementing a SaaS management platform helps you centralize and manage all your SaaS apps on a single dashboard. It gives a 360-degree overview of your SaaS environment, including application use, spending, user access, and security.

‍

‍

Constant surveillance helps you detect and manage possible vulnerabilities and unauthorized SaaS usage and shadow IT within your firm.

Streamlined SaaS application management gives you the insight to make cost-optimization decisions and ensure that your business adheres to security guidelines and standards. 

Streamlined SaaS application management gives you the insight to make cost-optimization decisions and ensure that your business adheres to security guidelines and standards.

Using a SaaS management platform has become an organization's go-to SaaS security standard strategy to prevent users from purchasing unsanctioned applications.

2. Enhance your authentication with SSO and 2FA

Integrating single sign-on (SSO) and two-factor authentication (2FA) significantly reduces the risks of using weak or repeated passwords and unauthorized access to your SaaS applications.

SSO requires users to provide one-time authentication to enable access to multiple apps. 

2FA provides an extra layer of protection by requiring users to provide additional verification, like a one-time password or biometric authentication.

3. Ensure that your vendors comply with security regulations

A Superoffice study claims that 60% of organizations believe that governance and compliance are their major concerns when dealing with cloud services.

Before implementing a SaaS app, assessing the vendor's security standards is critical. Before implementing a SaaS app, assessing the vendor's security standards is critical.

Check that they adhere to industry-standard security measures and laws such as the General Data Protection Regulation (GDPR), the Health Insurance Portability and Accountability Act (HIPAA), or the International Organization for Standardization (ISO) 27001.

‍

‍

‍

Assess the vendor's security policies, data handling methods, and certifications to guarantee that your data will be safeguarded in accordance with your organization's security standards.

Do not sign a contract with a vendor lacking common SaaS compliance certifications like GDPR and SOC 2. Otherwise, you might put your SaaS data security at risk, lose valuable customer and financial data, and lose revenue.

4. Encrypt your data

Encryption is critical to ensuring the security of sensitive data handled or transmitted through SaaS applications. As per Statista, 38 percent of businesses are specifically concerned about encrypting their organizations' data.

Encryption turns data into an unreadable format that can only be accessed by authorized individuals with the decryption key. Encrypting your data adds an extra layer of security, even if there is a breach.

‍

‍

‍

Ensure your data is encrypted during transit and at rest. The channels connected with SaaS apps often use Transport Layer Security (TLS) to safeguard data in transit. Some SaaS providers provide additional encryption features for data protection at rest.

Check each SaaS service to see whether data encryption is possible by default and, if so, activate it.

5. Prevent shadow IT with centralized procurement

G2 research shows that, by 2025, three in four people believe that shadow IT will be a bigger security issue at their companies.

Shadow IT is common in organizations with a disorganized procurement process. SaaS management platforms now have procurement workflows to automate the process and provide 100% transparency with real-time progress updates.

Implement a centralized procurement process and completely eradicate the risks of shadow IT . 

6. Manage user access effectively

Security Magazine says 31% of former employees still have access to an organization's SaaS applications and other sensitive information.

Another report from TechRepublic reveals that around 20% of organizations experienced data breaches by ex-employees.

This indicates the need for a streamlined user access management system. Users should be provisioned appropriately for suitable applications and deprovisioned right after they leave your organization. 

‍

‍

‍

‍

SaaS management platforms with user provisioning and deprovisioning modules can be integrated with your HRIS systems to collect user data, access, and permission levels in each application.

With a centralized access dashboard, you can easily provision the right apps to users when they join and revoke their access when they quit, preventing security breaches by former employees.

7. Implement strong IAM policies

Implementing strong identity and access management (IAM) policies is the most fundamental aspect of SaaS security best practices. IAM policies govern user access to SaaS applications and resources, ensuring only authorized individuals can view, modify, or interact with sensitive data.

By implementing robust IAM policies, organizations can enforce principles of least privilege, granting users access to the resources necessary for their roles and responsibilities. This reduces the risk of unauthorized access, data breaches, and insider threats.

Additionally, IAM policies enable organizations to streamline user provisioning and deprovisioning processes, ensuring that access rights are promptly revoked when employees leave the company or change roles.

8. Don't overlook SaaS security posture management

One critical SaaS security standard practice is not to overlook SaaS security posture management. It involves continuously assessing and monitoring the security configuration of SaaS applications and services to promptly identify and address vulnerabilities or misconfigurations.

Regularly reviewing and updating security settings, permissions, and configurations ensures that SaaS environments remain resilient against evolving threats.

By staying vigilant and proactive in managing the security posture of SaaS platforms, organizations can mitigate risks, safeguard sensitive data, and maintain compliance with industry regulations.

Ignoring this aspect of SaaS security best practices could leave businesses vulnerable to cyberattacks, data breaches, and other security incidents, emphasizing the importance of prioritizing security posture management in SaaS environments.
