Not possible - Spark has a very small footprint, see the specs, and is targeted at SMBs. GAiA runs on hardware supporting larger companies up to very large deployments with MDS, Maestro a.o. for ISPs and telecom providers. So harmonizing Spark is a wrong term - you can e.g. implement Cloud-Based services like TE on SMBs, but some features will never be supported; see https://support.checkpoint.com/results/sk/sk178604 for limitations, especially what is missing for both locally and centrally managed SMBs:
- Content Awareness
- Data Loss Prevention (DLP) Blade
- HTTP/HTTPS proxy
- Suspicious Activity Monitoring (SAM) Rules
- TLS 1.3
- RADIUS Accounting
- Mobile Access Web Portal
- Traditional VPN Mode
- Secure Configuration Verification (SCV) and Desktop policy
- Machine certificate authentication
- Autonomous Threat Prevention
- Threat Extraction Blade
- Monitoring Blade
- ClusterXL Load Sharing mode
- VRRP cluster
- MTA for Threat Emulation
- IPS Packet Capture
- Anti-Virus archive scanning
- IP Helper
- Anti-ARP spoofing
- 802.1w RSTP (Rapid Spanning Tree Protocol)
