Supercharge your ad network with performance and security

Web ads are often slow and unsafe, an undesirable web experience that drives users to download ad blockers, bypassing them completely. When ad blockers are used, or even when the ads are loaded slowly and users simply leave the page, advertisers and publishers lose out on crucial impressions.

Cloudflare’s Firebolt benefits publishers, advertisers, and end users by improving an ad network’s ability to serve ads faster, over a secure connection.


Features and Plans
Fast advertisement load time

Faster Ad Load Times

Cloudflare’s global network of 152 data centers in 74 countries, combined with routing and performance technologies, accelerates the delivery online ads to any device by up to 6 times faster.

Secure web advertisement

Increased Security

Firebolt mitigates malvertising by automatically enabling browser security features and cryptographically signing all ads. This reduces the risk of malware and other attacks, and ensures that all ads are delivered over HTTPS.

Optimised advertisement

Support for AMP for Ads

Accelerated Mobile Pages (AMP) allows publishers to create mobile optimized content that loads instantly. Firebolt enables independent ad networks to easily leverage the new AMP ad format.

Cloudflare was easy to setup, and we saw an impressive difference in the speed of ad delivery with Firebolt's support for AMP for Ads.

Firebolt Analytics (Coming Soon)

Gain insight into the total number of ads served. See how many end users viewed your ads. Analyze traffic in aggregate, within a specific scope of time, or get more granular by viewing on a per publisher basis.

Creating harmony in the Ad Tech Ecosystem

Prominent online publishers have reported advertising content to be 3 times heavier than their page’s editorial content. Each additional second of load time results in publishers seeing a 7% reduction in conversions.1 Millions of visitors have turned to ad blockers to help improve their experience and advertising organizations have estimates that by 2020 they will lose $27 billion dollars per year as a result.2

Cloudflare Firebolt helps everyone win by striking a balance between user experience and profitability. Fast loading pages create a better experience for visitors. Publishers improve profitability with increased visitor engagement, and ad networks serve their ads faster and safer.

Cloudflare is the only non-Google provider that can sign and validate AMP advertisements, extending the performance benefits of AMP to the ad viewing experience.

    With 152 data centers across 74 countries and 15 Tbps of capacity, Cloudflare’s Anycast network absorbs distributed attack traffic by dispersing it geographically, while keeping Internet properties available and performant.

    DNSSEC is the Internet’s non-spoofable caller ID. It guarantees a web application’s traffic is safely routed to the correct servers so that a site’s visitors are not intercepted by a hidden “man-in-the-middle” attacker.

  • Rate Limiting

    Rate Limiting protects critical resources by providing fine-grained control to block or qualify visitors with suspicious request rates.
  • SSL / TLS

    Transport Security Layer (TLS) encryption enables HTTPS connections between visitors and origin server(s), preventing man-in-the-middle attacks, packet sniffing, the display of web browser trust warnings, and more.
  • Secure Registrar

    Cloudflare is an ICANN accredited registrar, protecting organizations from domain hijacking with high-touch, online and offline verification for any changes to a registrar account.
  • Orbit

    Cloudflare Orbit solves security-related issues for Internet of Things devices at the network level.
  • Argo Tunnel

    Cloudflare creates an encrypted tunnel between its nearest data center and an application’s origin server without opening a public inbound port.
  • Workers

    Cloudflare Workers let developers run JavaScript Service Workers in Cloudflare's 152 data centers around the world.
  • Access

    Secure, authenticate, and monitor user access to any domain, application, or path on Cloudflare.
  • Spectrum

    Spectrum protects TCP applications and ports from volumetric DDoS attacks and data theft by proxying non-web traffic through Cloudflare’s Anycast network.
