One of the key benefits of SASE is its ability to unify network and security management into a centralized dashboard, providing real-time monitoring and visibility across all connected endpoints, applications, and cloud platforms.
- How it helps:
- Unified View: SASE provides a single-pane-of-glass interface for monitoring both network performance (via SD-WAN) and security events (via integrated security services like FWaaS, CASB, SWG, and ZTNA). This eliminates the need to manage multiple, disjointed tools.
- Real-Time Monitoring: IT teams can view network traffic, user activity, and security incidents across different locations in real-time, allowing for quick identification of bottlenecks, anomalies, or potential threats.
- Example: A network administrator can track traffic flows from a branch office, detect potential threats in a remote worker’s connection, and monitor application performance in a cloud environment, all from a single dashboard.
2. End-to-End Visibility Across Cloud, On-Premises, and Remote Environments
SASE provides end-to-end visibility across hybrid environments, including on-premises data centers, cloud services, and remote workers. This comprehensive visibility helps organizations understand traffic patterns and monitor network performance, regardless of user location or infrastructure type.
- How it helps:
- Cloud-Native Visibility: With cloud services like AWS, Azure, and Google Cloud being integral to many organizations, SASE allows for visibility into cloud-based applications and data flows, ensuring secure, optimized access.
- Remote Worker Insights: As remote work grows, SASE provides visibility into remote user behavior, tracking what applications are being accessed, how they’re performing, and whether they’re following security policies.
- Example: A security team can monitor data flows between a cloud SaaS application and users across branch offices and remote locations, ensuring compliance with policies while analyzing performance across regions.
3. Granular Application and User-Level Visibility
SASE enhances granular visibility by allowing IT teams to monitor individual users, devices, and applications in detail. This level of insight helps track exactly who is accessing which applications, when, and from where, improving security and performance monitoring.
- How it helps:
- Application-Aware Visibility: SASE solutions, particularly through SD-WAN, offer application-level visibility, allowing IT teams to see which applications are consuming the most bandwidth, their performance, and whether they’re secure. This includes both traditional on-premises apps and cloud-native SaaS applications.
- User Behavior Insights: SASE tracks individual user behavior across the network, providing insights into user activities and identifying potential anomalies or risky behavior.
- Example: If an employee accesses a CRM application in Salesforce, the IT team can monitor the latency, bandwidth usage, and security risks associated with the connection, ensuring both optimal performance and compliance with security policies.
4. Real-Time Threat Detection and Analytics
SASE integrates multiple security services, such as Firewall-as-a-Service (FWaaS), Intrusion Prevention Systems (IPS), and Secure Web Gateways (SWG), which offer deep packet inspection, behavioral analysis, and threat intelligence. These features help detect threats in real-time while offering visibility into network vulnerabilities.
- How it helps:
- Behavioral Analytics: SASE platforms use machine learning and AI to analyze network traffic and detect anomalous behavior. These analytics can flag unusual patterns, such as a sudden spike in data usage or attempts to access restricted applications.
- Automated Threat Detection: SASE continuously scans traffic for malware, phishing attempts, or intrusions, offering automated alerts and responses. This increases visibility into threat landscapes and helps organizations respond faster to potential security incidents.
- Example: A SASE platform can detect an employee inadvertently downloading malware from a phishing website and immediately flag the activity, providing details on the user, the device, and the threat source.
5. Improved Visibility into Data Movement and Compliance
SASE solutions include tools like Data Loss Prevention (DLP) and Cloud Access Security Brokers (CASB), which provide visibility into how sensitive data moves across the network and whether it’s handled according to compliance policies.
- How it helps:
- Data Movement Tracking: SASE tracks how data flows between cloud environments, on-premises systems, and endpoints, identifying who accessed what data, where it’s stored, and if it was shared with unauthorized users.
- Compliance Visibility: For organizations that need to comply with regulations like HIPAA, GDPR, or PCI-DSS, SASE provides visibility into compliance violations (e.g., sharing sensitive information without encryption) and ensures that security policies are enforced across all locations.
- Example: If a file containing sensitive customer information is uploaded to an unsanctioned cloud storage platform, SASE’s DLP capabilities can immediately flag the violation, offering details on the user and the data involved.
6. Visibility into Shadow IT
Shadow IT refers to unauthorized applications and services used by employees without the approval or knowledge of the IT department. SASE, particularly with CASB integration, helps organizations detect and manage shadow IT by providing visibility into all applications being accessed and used within the network.
- How it helps:
- Application Discovery: SASE helps identify all SaaS applications and cloud services used within the network, even those that haven’t been officially sanctioned by IT. This prevents unsanctioned apps from becoming security risks.
- Control Over Unsanctioned Applications: Once shadow IT is discovered, SASE allows IT teams to either block unsanctioned apps or apply security controls, ensuring that sensitive data is not exposed through unauthorized applications.
- Example: An employee using an unsanctioned file-sharing platform like Dropbox to share company data can be flagged by SASE, allowing IT to either block access or enforce security measures.
7. Visibility into Encrypted Traffic
Many threats are hidden in encrypted traffic that traditional security solutions can’t inspect without sacrificing performance. SASE integrates decryption capabilities, allowing organizations to maintain visibility into encrypted traffic while ensuring that threats are detected and blocked.
- How it helps:
- SSL Decryption: SASE decrypts SSL/TLS traffic to inspect it for malware, unauthorized data transfers, or security risks without slowing down the network.
- Comprehensive Threat Visibility: By inspecting encrypted traffic, SASE ensures that malicious activity doesn’t go unnoticed, particularly as more web traffic becomes encrypted by default.
- Example: A user downloads an encrypted file from a suspicious website, and SASE decrypts the traffic, detects a potential malware threat, and alerts IT while blocking the download.
8. Contextual and Identity-Based Visibility
SASE’s Zero Trust Network Access (ZTNA) capabilities ensure that network access is based on identity, context, and device posture. This allows IT teams to gain visibility into who is accessing what resources, from where, and under what conditions, ensuring access control is aligned with business needs and security policies.
- How it helps:
- Identity Visibility: SASE tracks access by user identity and device posture, offering insight into who is accessing applications and services, whether from remote locations, branch offices, or cloud environments.
- Contextual Awareness: IT teams can monitor contextual factors like geolocation, device type, and time of access, ensuring that access is granted based on dynamic conditions and is logged for future analysis.
- Example: If a remote worker attempts to access sensitive financial data from an unusual location or an unsecured device, SASE can flag the attempt, offering full visibility into the identity, location, and context of the access request.
9. Automation and Alerting for Incident Response
SASE improves network visibility by providing automated alerts and incident reports based on predefined security policies. When a potential issue or anomaly is detected, IT teams are alerted immediately and provided with detailed insights for faster incident response.
- How it helps:
- Automated Alerts: SASE platforms can automatically generate alerts when suspicious behavior or policy violations occur, providing real-time notifications for quicker responses.
- Detailed Incident Reports: For every security incident, SASE provides detailed logs and reports, showing exactly what happened, when, and where, allowing IT teams to respond effectively.
- Example: If a user tries to upload a sensitive file to a personal cloud storage account, SASE will automatically flag the activity, notify the IT team, and provide detailed logs of the user identity, device, time, and location of the incident. This enables the IT team to take immediate action, such as revoking access or quarantining the device, and ensuring that sensitive data remains secure.
10. Improved Visibility for Remote and Hybrid Workforces
As organizations increasingly adopt remote and hybrid work models, ensuring visibility into the behavior and activities of remote workers becomes essential. SASE provides comprehensive visibility into the traffic generated by remote workers, ensuring that they follow corporate security policies regardless of their location.
