Key features
Beyond antivirus: a complete endpoint security platform managed from a unified console.
Behavioural detection
Analyses every process in real time. Detects fileless malware, living-off-the-land (LOL) attacks, process injection and advanced evasion techniques.
Anti-ransomware + Rollback
Detects suspicious encryption processes, blocks them in real time and automatically restores affected files via shadow copies. No ransom paid.
Threat Hunting & Timeline
Endpoint event history (up to 6 months). Graphical attack chain visualisation. Customisable EDR queries for investigation.
Application & device control
Application whitelist/blacklist. USB, Bluetooth, network printer blocking. Centralised endpoint firewall rules. Full software inventory.
On-premise or cloud
GravityZone console hosted in your datacenter (sovereign data) or Bitdefender SaaS. Windows, macOS, Linux agents. Proxmox/VMware/Hyper-V hypervisors.
First-level support + publisher MDR
Convergent provides first-level support: deployment, configuration, alert follow-up. The MDR (Managed Detection & Response) service is delivered by the publisher's specialist teams (Bitdefender / Avast).
Bitdefender vs Avast Business — which to choose?
Convergent advises you based on your sector, size and regulatory constraints.
Bitdefender GravityZone
Ideal for: banks, healthcare, industry, organisations ≥50 seats. Full EDR/XDR, anti-ransomware rollback, advanced threat hunting, NIS2/ISO 27001 compliance. On-premise console available.
Avast Business
Ideal for: SMEs up to 200 seats, retail, services. Simple deployment, low footprint, integrated cloud + email protection. Excellent cost-protection ratio for constrained budgets.
Our recommendation
Convergent conducts an audit of your endpoints, regulatory constraints and budget before recommending a solution. Setup includes deployment, policy configuration and IT team training.
Frequently Asked Questions
What is the difference between antivirus, EDR and XDR?
An antivirus detects known signatures. An EDR (Endpoint Detection & Response) analyses behaviour in real time, detects unknown threats and enables automated response (isolation, rollback). An XDR (Extended Detection & Response) correlates endpoint + network + email + cloud data for unified visibility across your entire infrastructure.
Does Bitdefender GravityZone protect against ransomware?
Yes. GravityZone includes a specific anti-ransomware module (Ransomware Remediation) that detects suspicious encryption processes, automatically blocks them and performs a rollback of affected files via shadow copies. AV-TEST and AV-Comparatives tested: 100% detection in 2024.
Is EDR compatible with virtualised environments (Proxmox, VMware)?
Yes. Bitdefender GravityZone supports lightweight virtualisation via Security Server (centralised agent per hypervisor host). Compatible with Proxmox VE, VMware vSphere, Citrix Hypervisor, Hyper-V. VMs share a common signature cache — significant memory footprint reduction.
Do data leave Tunisia with the cloud version?
With GravityZone Cloud, data is hosted in Bitdefender datacenters (EU). For organisations subject to sovereignty obligations (banks, public bodies), Convergent recommends the on-premise version with locally hosted console. No business data is transmitted — only threat metadata is sent to Bitdefender cloud.
Why EDR becomes essential for Tunisian enterprises
Cybercrime targeting Tunisian organizations is experiencing exponential growth. Advanced endpoint protection is no longer optional.
Rising threats
According to ANCS (National Cybersecurity Agency), reported incidents increased from 63,000 in 2020 to 558,000 in 2025, representing a 785% rise. Ransomware attacks have multiplied by 25 over the same period.
Critical sectors targeted
Cybercriminals primarily target the financial sector, industrial infrastructure, and public services. Attack techniques are evolving: banking phishing, fileless malware, supply chain compromise.
Regulatory requirements
The Central Bank of Tunisia (BCT) imposes strict cybersecurity requirements for financial institutions. The European NIS2 directive applies to subsidiaries of Tunisian companies operating in the EU. ANCS recommends EDR adoption for critical organizations.
Our EDR deployment methodology
Convergent applies a structured approach to minimize disruptions and maximize your endpoint protection effectiveness.
Current state audit
Complete endpoint inventory — Operating systems, critical applications, business constraints. Current security posture assessment via our free audit tool. Analysis of regulatory requirements specific to your sector.
Pilot phase
Deployment on 10-15 test workstations representative of your environment. Policy configuration adapted to your business flows. Compatibility testing with your critical business applications. Performance validation and threshold adjustment.
Progressive rollout
Group-based deployment (management → IT → end users). Smooth migration from your existing antivirus. Continuous monitoring of performance and alerts. Rule adjustment based on field feedback.
Training & handover
Administrator console training for your IT teams. Response procedures for alerts and incidents. Complete documentation in English and French. Ongoing support during ramp-up period.
Indicative timeline
Audit: 3-5 business days • Pilot phase: 1 week • Full deployment: 2-4 weeks depending on fleet size • Training: 2 sessions of 2h • Stabilization: 2 weeks of support
Executive questions about EDR
Will EDR slow down our workstations?
Modern solutions (Bitdefender, Avast) are optimized for minimal impact: <2% CPU usage in normal operation, <150 MB RAM per endpoint. Analysis modules activate only when detecting suspicious behavior. We configure exclusions for your critical business applications.
What return on investment to expect after 6 months?
EDR prevents costly security incidents. According to IBM Security, the average cost of a breach in 2025 amounts to $4.88 million USD. A properly configured EDR solution significantly reduces this risk. Convergent sizes the solution according to your budget and business priorities.
Can our IT teams manage EDR autonomously?
Yes, after training. The Bitdefender GravityZone console is intuitive — unified dashboard, automatic reports, guided incident response. For organizations without internal security expertise, the vendor's MDR (Managed Detection & Response) service can handle 24/7 analysis and response.
Is EDR sufficient or do we need other security solutions?
EDR protects endpoints but is part of a global strategy. Convergent also recommends: next-generation firewall (OPNsense), immutable backup solution (TrueNAS), user anti-phishing training, and regular configuration audits. We design coherent security architecture.
Protect your endpoints today
44% of ransomware attacks start with an unprotected endpoint (Verizon DBIR 2025). Convergent deploys your EDR solution within 5 business days.
