As artificial intelligence agents, automated services and malicious bots reshape the internet, Estonia based technology company Blackwall is positioning itself at the centre of a growing infrastructure challenge. The web traffic management platform has raised $100 million in a Series C funding round at a valuation of $2.2 billion, strengthening its ambition to build a global ecosystem that helps hosting providers manage, protect and monetise internet traffic.
A Major Funding Milestone
The Series C round was led by AVP, with participation from existing investors Dawn Capital, MMC Ventures and Tera Ventures. The latest investment marks a significant step in Blackwall’s expansion as demand grows for technology that can distinguish legitimate visitors and automated services from malicious traffic.
The company had recently attracted attention in Estonia’s technology sector after reaching a reported valuation of €1 billion and ranking fifth in the TopTech 2026 list of the country’s most valuable technology companies. Its new valuation of $2.2 billion highlights investor confidence in the future of web security and traffic management.
Tackling the Internet’s Bot Problem
Websites increasingly receive traffic from sources beyond human visitors. Search engine crawlers, automated business tools and emerging artificial intelligence agents interact with online services, while malicious bots can exploit the same infrastructure for scraping, fraud, credential attacks and other forms of abuse.
Blackwall aims to address this complexity through its traffic filtering and security platform. Its technology operates within hosting providers’ infrastructure, analysing incoming requests and filtering harmful activity before it reaches websites and applications.
According to the company’s official website, its GateKeeper platform combines bot mitigation, distributed denial of service protection, a web application firewall, traffic filtering and performance optimisation. These capabilities are designed to protect websites while allowing legitimate traffic to continue flowing.
Why Hosting Providers Matter
Blackwall’s strategy centres on partnerships with web hosting companies, managed service providers and cloud infrastructure operators. These businesses support millions of websites and applications, making them an important point of access for deploying security technology at scale.
Rather than competing directly with hosting providers for their customers, Blackwall integrates its platform into their existing infrastructure. This approach allows providers to offer additional security services, improve customer retention and create recurring revenue opportunities.
The model is particularly relevant in a fragmented hosting market, where businesses depend on providers that understand their technical requirements and operational needs.
Preparing for the Agentic Web
The rapid development of artificial intelligence is creating another challenge for online infrastructure. AI agents can perform searches, retrieve information and interact with digital services at a scale that differs significantly from traditional human browsing.
While legitimate automated activity can improve productivity and enable new services, poorly controlled agents and malicious automation can overwhelm systems, consume resources and increase security risks.
Blackwall wants to help infrastructure providers prepare for this shift by expanding its traffic management capabilities. Its broader vision is to connect providers, infrastructure and technology within an ecosystem capable of handling increasingly automated internet activity.
Global Expansion on the Roadmap
The company plans to use its new funding to expand its international presence, deepen its technology platform and establish or strengthen operations across 12 strategic regions in North America, Europe, Asia Pacific and the Middle East.
The investment will support Blackwall’s efforts to serve a wider network of hosting and infrastructure providers as demand for advanced traffic security grows.
What Comes Next?
Blackwall’s fundraising reflects a wider change in how businesses think about internet infrastructure. Website protection is no longer limited to blocking cyberattacks. It increasingly involves managing automated traffic, maintaining performance and ensuring that online services remain accessible as digital activity expands.
With $100 million in fresh capital and a $2.2 billion valuation, Blackwall is betting that the next generation of the internet will require a new layer of traffic management, one capable of protecting websites while making room for legitimate human and AI driven activity.
