A Closer Look at Hostzop’s Enterprise Cloud Security Architecture
In the era of advanced digital transformation, cloud infrastructure is no longer a choice—it's a critical backbone for every enterprise. As cyber threats grow in volume and complexity, enterprises demand a cloud environment that delivers flexibility, performance, and uncompromising security across every layer.
Hostzop's Enterprise Cloud Security architecture addresses this challenge head-on with a meticulously crafted multi-layered defense system, underpinned by hardened virtualization, software-defined networking, distributed Ceph storage, physical data center security, clean ISP-grade bandwidth, and a robust inbuilt firewall system available to every user by default. This page offers a deep technical dive into how Hostzop Cloud ensures operational safety and enterprise-level control.
Secure-by-Design Architecture (OpenStack-based)
At the heart of Hostzop Cloud is OpenStack — an enterprise-grade, modular IaaS platform known for its granular policy controls and security enforcement across compute, storage, and networking layers.
- KVM-Based Virtualization (Kernel-based Virtual Machine): Provides native CPU virtualization via hardware-assisted virtualization (Intel VT-x / AMD-V), reducing the risk of hypervisor escape and ensuring complete tenant isolation.
- Libvirt and QEMU Integration: Ensures low-level VM control with secure hooks, image validation, and signed kernels.
- Host Hardening: All hypervisors are locked down with hardened Linux distributions, mandatory SELinux/AppArmor enforcement, restricted root access, SSH key-based authentication, and audit logging.
- Live Kernel Patching: Apply security updates to the kernel without rebooting the VM host, preserving uptime and minimizing vulnerability windows.
- Nova API Access Control: Enforced via Keystone and policy.json roles, ensuring only authorized users can manage compute resources.
Built-In Cloud Firewall – Always On, Free, and Configurable
Every Hostzop VM is protected by an enterprise-grade cloud firewall — always on, fully configurable, and included free with every instance. No hidden charges, no surprise bills.
Configure and manage firewall rules from our dashboard or via API with complete transparency and control — no need to depend on 3rd-party agents or inflated cloud billing.
Default Deny-All Policy
All traffic is blocked by default — inbound and outbound — until you explicitly allow it.
Granular & Protocol-Level Control
Allow specific ports/protocols (e.g., TCP 80, ICMP, MySQL, SSH) on per-instance basis. Supports TCP, UDP, ICMP and more.
Global or IP-Specific Rules
Apply rules to all IPs or limit to precise source/destination CIDRs for surgical security.
Logging and Auditing
All rule changes are logged with timestamps for audit trails and rollback confidence.
Real-World Examples:
- Allow HTTP (TCP 80) from
0.0.0.0/0 - Allow SSH (TCP 22) from
203.0.113.10(corporate VPN) - Allow MySQL (TCP 3306) outbound to
10.0.2.0/24private DB subnet
Even if your app layer is misconfigured, your VM’s network layer stays locked down unless you explicitly open it — ensuring the ultimate fail-safe.
Distributed and Secure Storage with Ceph
Hostzop Cloud uses Ceph as the core for both block and object storage, offering scale-out, resilient, and high-performance storage with built-in replication and integrity verification.
- RBD (RADOS Block Device): Ceph's native block storage provides thin provisioning, live snapshotting, and cloning capabilities.
- Triple Replication (3x): Every data object is stored in three different nodes, ensuring data durability even in case of hardware failure.
- CRUSH Algorithm: Determines data placement using deterministic hashing—no central metadata servers means lower risk and better scalability.
- Encryption at Rest: Each volume is encrypted using LUKS or dm-crypt standards with tenant-specific keys.
- S3-Compatible Object Storage: Ideal for backups, logs, and archives with full bucket-level ACLs and pre-signed URL controls.
- Storage QoS and IOPS Limiting: Prevent noisy neighbors from impacting performance via fine-grained storage throttling.

- Redundant power (N+N UPS), chilled water HVAC (4-pipe system), and 99.98% uptime SLA
Software-Defined Networking with Advanced Controls
Powered by Tungsten Fabric, Hostzop Cloud's SDN layer brings granular control over network topology, traffic flow, and security policy enforcement.
- Micro-Segmentation: Enforce workload isolation using virtual routers and security groups. Traffic between VMs is allowed only if explicitly permitted.
- Distributed Firewall (DFW): Stateful packet inspection and connection tracking are enforced at each vNIC.
- Floating IP NAT: Allocate public IPs without exposing internal networks.
- VPN-as-a-Service (VPNaaS): Deploy secure site-to-site IPsec VPN tunnels.
- LBaaS (Load Balancer): Auto-scaled traffic distribution with health checks.
- Port Forwarding and DNAT: Control granular access without exposing the entire VM.
- QoS and Rate Limiting: Network traffic shaping to enforce bandwidth caps or prioritize critical traffic.
Clean Bandwidth – Carrier Neutral and Route-Optimized
Our cloud is built on clean, enterprise-grade network lines to deliver predictable performance and mitigate risk from polluted routes.
- 2 Gbps Default Uplink per VM Node
- Carrier-Neutral Connectivity: TATA, Jio, and Ishan provide redundant fiber paths.
- BGP Routing with Failover: Auto-routing for high availability and low latency.
- Private VLAN Isolation: Each project/tenant gets dedicated L2 segments.
- Public & Private Interfaces: Separate NICs for private traffic and public exposure.
Host-Based and Perimeter-Level Firewalls
- PfSense Firewall: 1-Click App Deployment
- Dedicated Firewall VM: Launch one per project
- Security Features: Stateful inspection, NAT, VPN tunneling, QoS, and packet filtering
- IDS/IPS: Integration with Snort or Suricata
- Advanced Rules: Schedule-based rules, geo-blocking, and aliasing
When used alongside the built-in Hostzop firewall, PFsense offers an additional layer for enterprises needing perimeter-level gateway security and traffic routing.
