Technically, both are strong. Kaspersky's protection is 8.7; Bitdefender's is 9.7. But Kaspersky was banned from US consumer sale on September 29, 2024, and its corporate headquarters remain under Russian legal jurisdiction regardless of where its data centers are located. That constraint is the delta, not the detection engine.

What you get that Kaspersky can't offer

Global availability — including the US market, where Kaspersky cannot be purchased or activated by new customers.

A privacy score that reflects the actual situation: 8.7 vs Kaspersky's 2.4. Kaspersky's infrastructure is EU-hosted, but Russian corporate jurisdiction applies regardless. Bitdefender operates under Romanian law with EU GDPR coverage.

Ransomware rollback — Kaspersky's remediation layer doesn't include automatic file recovery after encryption.

What you give up

Value per feature. In markets where Kaspersky is available, its bundle value score is 8.6 vs Bitdefender's 7.7.

What you get that Bitdefender doesn't offer

Strong bundle value in markets where the product is available — competitive feature depth at a lower price point than Bitdefender.

What you give up

US availability. New US purchases and activations were banned as of September 29, 2024. Existing US users were silently migrated to UltraAV via a background update without explicit consent when the ban took effect.

Neutral legal jurisdiction. Kaspersky's Russian corporate structure subjects the company to Russian government legal authority — independent of where servers are physically located. BSI (Germany) and FCC (US) have both issued formal advisories.
