BlazingCDN

Poland· Web Hosting and Cloud Computing

Needs review

Shortlist when you need a Polish-contracted, high-volume HTTP CDN for VOD, software downloads, or pre-encoded HLS and you can live with a delivery-first product. Skip when you need WebSockets, origin DDoS, or a WAF in the same console. Consider Cloudflare for the security platform, or OVHcloud if you want European compute and CDN under one group.

KeyCDN

Switzerland· Web Hosting and Cloud Computing

Needs review

Shortlist KeyCDN when you want a Swiss-contracted, pay-as-you-go CDN with Pull Zones, Push storage in European data centers, and a REST purge API, and you can accept global (including US) edge caches. Skip it when you need Cloudflare-class WAF, DNS, or Zero Trust, or a written US-free cache path. Consider Cloudflare for platform breadth.

BlazingCDN

Anycast pull cache for static assets
Create a zone, point it at your origin, and cache on demand at the nearest advertised edge. The vendor claims a 96%+ average hit ratio and HTTP/2, HTTP/3, Brotli, IPv6, purge API, and origin shield. Product copy caps Anycast files at 70 MB and sends multi-GB installers to Video CDN.
Video CDN with in-network replication
Large files are copied inside the CDN across Europe, Asia, and America according to the products page, so delivery need not hit the origin after import. Docs mention auto-import, range requests, cache warming, and a permanent cache option. One Video CDN FAQ also claims HLS/DASH transcoding, which conflicts with the Streaming CDN page.
HLS and LL-HLS delivery without packaging
Streaming CDN is a delivery layer for pre-encoded HLS, LL-HLS, and DASH from your own media server. The company claims 2 to 4 second glass-to-glass latency on LL-HLS versus 20 to 40 seconds for standard HLS. You bring the encoder. Live event broadcasts still need prior provider approval.
Signed URLs, tokens, and geo filters
HMAC-signed links with expiry, per-request tokens, referrer and user-agent filters, and country or IP allowlists and blocklists are listed as available on all account sizes. DRM-encrypted segments are delivered as-is. Licensing stays in your stack.
Object storage origin plus zone API
Buckets can be created with S3 or Swift protocols and used as a CDN origin. Help docs cover FTP, SFTP, rclone, and OpenStack Swift uploads. Public API docs exist for zone management and purge from CI. Image optimization is marked coming soon.

KeyCDN

Pull Zones with instant purge
A Pull Zone fetches from your origin and caches on KeyCDN edges. The dashboard and REST API can purge a whole Zone or selected URLs. Zone changes are described as taking a few minutes globally. Best for sites and apps whose origin already holds the objects.
Push Zones on European storage
A Push Zone uploads via FTP(S) or rsync over SSH into KeyCDN's storage cluster. Official FAQ: required for files larger than 100 MB. The storage page states objects rest in European data centers; edges then cache globally. Interconnect from storage to edges is unmetered; you pay storage plus egress.
Origin Shield (US East, US West, Amsterdam)
An extra cache layer collapses origin requests (keep-alives, collapsed forwarding). Documented shield sites are United States East Coast, United States West Coast, and Amsterdam, chosen automatically. This cuts origin load. It also means a miss can be fetched through a US shield, not only through Amsterdam.
Query-string image processing
On a CDN URL you can set width, height, quality, format (including WebP), grayscale, and flip/flop. Transforms are billed per operation (see the official pricing page). Useful for CMS teams that do not want a separate image pipeline.
REST API, TLS choices, and protocol stack
The API manages Zones, purge, and traffic reports. Every account can attach Let's Encrypt, a shared cert, or a custom cert. Product pages list HTTP/2, TLS 1.3 (with 0-RTT in KeyCDN's TLS blog), Gzip, optional Brotli when the origin already emits br, IPv6, and IP anycast plus latency-based routing.
Token, referrer, and account locks
Secure Token and Zone Referrer (hotlink protection) limit who can fetch a URL. Account-side controls include two-factor authentication and IP access rules. These are CDN access controls, not a full WAF or Zero Trust product.

Assurance & compliance: BlazingCDN vs KeyCDN

Independent security / no-logs audit	Not found Searched official site, legal page, features, and help centre. No third-party audit PDF or no-logs report.	Not found No public third-party audit PDF found on keycdn.com. Dashboard logs are said to anonymize client IPs; raw syslog format includes an IP field.
ISO 27001	Not found No ISO 27001 claim or certificate found on primary pages.	Not found Network page mentions ISO 27001 for premium data centers. That is not a published ISO 27001 certificate for proinity LLC.
SOC 2 / SOC 3	Not found No SOC 2 or SOC 3 report found.	Not found Searched official legal, network, and GDPR pages. No SOC 2 or SOC 3 claim found.
GDPR / EU data protection	Vendor claimed Polish VAT-registered entity; dedicated GDPR page treats the vendor as processor. Dedicated EU cache servers sold separately. Default Video/storage products replicate outside the EU.	Vendor claimed Swiss entity; GDPR page describes controller/processor roles, anonymized dashboard logs, and a DPA via support. Privacy Policy last updated 2018 still cites Privacy Shield for third parties.

Considerations & known limitations: BlazingCDN vs KeyCDN
Considerations & known limitations	BlazingCDN	KeyCDN
DDoS cover is for cached objects	High Help docs say protection is tailored to cached content. Uncached origin paths and dynamic sites can still be taken down. Pair with a dedicated mitigation product if origin availability is the requirement.	Non indicato
Default replicas include the US and Asia	Medium Video CDN and Cloud Storage advertise three-continent copies, including USA data centers. EU-only delivery is a separate GDPR Cache Servers SKU, not the default.	Non indicato
US-group billing and CRM tools	Medium Stripe and PayPal process top-ups. HubSpot is used for sales meetings. No published subprocessor list. Account metadata is not EU-only even if you pin caches.	Non indicato
No public audit, ISO, SOC, or DPA	Medium Procurement teams that need a cert pack will stall. MSA text also conflicts with the GDPR page on whether personal data is processed.	Non indicato
No WebSockets, VPN, or unapproved live events	Medium HTTP(S) delivery only. Live broadcasts need rights paperwork and prior approval. Anycast file size is capped at 70 MB on the product page.	Non indicato
Polish HQ plus Cyprus partner, shared MSA wording	Low Contact lists two companies. Legal-information MSA hyperlinks advancedhosting.com. Confirm which entity invoices you and which terms apply.	Non indicato
US cache copies and US Origin Shield	Non indicato	Medium Public PoP list includes many US cities. Origin Shield is documented in US East, US West, and Amsterdam with automatic selection. A Swiss contract does not keep objects out of the United States.
No current named subprocessor list	Non indicato	Medium Privacy Policy (May 2018) mentions an unnamed email provider and Privacy Shield. Payments include PayPal. Data-center brands are not named. Ask for a current list before treating transfers as mapped.
No public operator ISO 27001 or SOC 2	Non indicato	Medium ISO 27001 is mentioned for data centers, not as a verified proinity LLC certificate. No SOC 2 found. Security questionnaires will need vendor follow-up.
Privacy Policy last updated 2018	Non indicato	Medium The public policy still refers to Privacy Shield, which is not a current EU-US transfer framework. Confirm what actually applies in the DPA.
Push Zone required above 100 MB	Non indicato	Low Official FAQ: content larger than 100 MB must use a Push Zone (upload to KeyCDN storage), not a simple origin pull.

Idoneità

BlazingCDN

Best fit when

OTT or VOD teams that want large files replicated inside the CDN so the origin can leave the delivery path
Software and game publishers shipping installers or patches over HTTP(S) with signed URLs
AdTech or MarTech delivery of tags, scripts, and VAST where latency and EU invoicing matter more than a WAF
Sports or live HLS operators who already have a packager and want LL-HLS delivery, not transcoding
Teams running a multi-CDN or backup-CDN trial against an existing provider

Poor fit when

Products that need WebSockets, VPN tunnels, or generic TCP/UDP forwarding at the edge
Sites that need origin DDoS, WAF, bot management, and authoritative DNS in one console
Workloads that must stay EU-only by default without buying a dedicated GDPR cache footprint
Live event broadcasts without rights paperwork and prior provider approval
Buyers who require a public ISO 27001 or SOC 2 pack and a published subprocessor list before RFP

Consider instead when

When: You need DNS, WAF, bot management, Workers, and origin DDoS in one platform
Consider: Cloudflare
Broader US-headquartered edge platform. BlazingCDN is delivery-first and only claims DDoS cover for cached objects.
When: You want European compute, object storage, and CDN under one group with a public DC catalogue
Consider: OVHcloud
French-group IaaS plus CDN. Less specialised for high-volume VOD replication than BlazingCDN marketing claims.
When: You mainly need German-group web hosting with CDN as an add-on
Consider: IONOS
Closer if the origin stack is IONOS hosting rather than a specialist video CDN.

KeyCDN

Best fit when

Web and CMS teams that need a conventional pull CDN plus instant URL purge from a REST API
Software, game, or video distribution that must use Push Zones for objects larger than 100 MB
Buyers who want a Swiss contracting entity (proinity LLC) and prepaid credits instead of an annual CDN commit
WordPress sites that can use the official CDN Enabler URL-rewriting plugin
Stacks that only need edge cache, TLS, and token/referrer locks, not a bundled WAF or Zero Trust suite

Poor fit when

Organizations that require a contractual ban on US cache copies or US Origin Shield
Teams that need Cloudflare-style WAF rules, Workers compute, authoritative DNS, or Zero Trust in one vendor
Buyers who will not proceed without a current named subprocessor list and an operator-level ISO 27001 or SOC 2 report
Anyone expecting a self-hosted KeyCDN edge; the network is hosted-only

Consider instead when

When: You need WAF, bot management, Workers-style compute, authoritative DNS, or Zero Trust beside the CDN
Consider: Cloudflare
KeyCDN is a CDN specialist. Its Cloudflare-alternative page even describes multi-CDN pairing rather than feature parity.
When: Legal requires EU-only cache and shield, with no US PoP copies
Consider: Self-hosted cache (nginx or Varnish) in EU regions, or another CDN that publishes an EU-only region lock
KeyCDN lists many US cities and documents Origin Shield in two US coasts plus Amsterdam. Swiss HQ does not pin the cache.
When: You need a current operator ISO 27001 or SOC 2 report before onboarding
Consider: A CDN or cloud edge vendor that publishes those certificates
KeyCDN mentions ISO 27001 in a data-center context. No proinity LLC certificate or SOC 2 report was found on the official site.

Open questions for due diligence

BlazingCDN

Which legal entity issues the invoice and signs the DPA: Advanced Administrations Sp. z o.o. or BCDN LTD?
Is there a written DPA with Article 28 clauses, SCCs, and a current subprocessor list?
Can Video CDN or Cloud Storage be pinned to EU regions without the separate GDPR Cache Servers SKU?
Where are control-panel logs, raw logs, and Graylog exports stored, and for how long?
Does Video CDN transcode, or is packaging limited to Streaming CDN as that page states?
What is the contractual SLA (marketing copy uses both 99.999% and 99.998%) and what credits apply?

KeyCDN

Will KeyCDN name all subprocessors, colo providers, and payment/email processors in a current list?
Can a customer pin cache and Origin Shield to EU/Amsterdam only, in contract?
Does proinity LLC hold ISO 27001 or SOC 2, and can the reports be shared under NDA?
Does syslog log forwarding include client IPs, and is that processing described in the DPA?
Has the May 2018 Privacy Policy been replaced internally, and what transfer tool replaced Privacy Shield?
