Detailed Review
Neterra approaches DDoS protection as a carrier. Its site calls it a global telecom operator with more than 220 points of presence, and the DDoS service sits under its rental-of-resources offering next to connectivity and hosting.
The DDoS page says the cloud platform can protect against attacks larger than 2 Tbps and that a security platform filters malicious traffic so only legitimate packets reach the customer network. The provider in its general terms is Neterra EOOD, headquartered in Sofia, Bulgaria.
Filtering plus Smart Blackholing
The service is described as covering layer 3 to layer 7 attacks. A second mechanism, Smart Blackholing, is fully automatic and detects and redirects attacks, although the page gives no timing for it.
Support is stated as 24/7 proactive monitoring and professional support, without an SLA document on that page.
Certifications on the operator
The footer links ISO 9001, ISO 20000-1, ISO 27001, ISO 50001 and ISO 22301 certificates, and a PCI-DSS certificate dated 19 December 2025. These certify the company rather than the DDoS service itself.
Ask whether the DDoS platform falls inside the ISO 27001 scope if your procurement team requires it.
Regional strength
The DDoS page refers to attacks from the international and the Bulgarian Internet space and lists the international network, national network and Sofia Metro Fiber Network among its assets. That regional anchoring is useful if your users are in Bulgaria or the Balkans.
It also means a customer elsewhere in Europe should check latency and the routing path before committing.
Limitations to Consider
Neterra publishes no price, no mitigation time, no SLA and no list of scrubbing locations on its DDoS page, and the 2 Tbps figure is a statement about the platform, not a guarantee per customer. The site is thinner in English documentation than larger vendors. For published plans and SLAs compare Gcore or Link11.
Who Should Use Neterra
Operators and companies connected in Bulgaria or the Balkans who want carrier-based filtering from a Bulgarian entity and are fine with a quote-based purchase.
