Among the 10 most recent “Series Unknown” privacy and security rounds shown, only two disclosed amounts appear ($12M for StackHawk on 2025-05-22 and $4M for Liberty Defense on 2024-08-22, with SafeGuard Privacy at $500K on 2023-12-12). StackHawk’s $12M is the largest disclosed round and it is substantially above the rest of the disclosed amounts, while the majority of entries are undisclosed (8 of 10). The disclosed amounts also cluster in a mid-to-late window: StackHawk (May 2025) and Liberty Defense (Aug 2024) bracket a broader list that spans 2023-08-15 (Global Guardian) through 2025-06-05 (Noma).
Geographically, the list shows a two-country skew (Israel appears via Noma on 2025-06-05, Piiano on 2024-04-01, and also at least one other Tel Aviv-area presence via Noma), while the largest disclosed amounts come from the U.S. (StackHawk in Denver; Liberty Defense in Vancouver, British Columbia is Canada). Dates are concentrated in the last 18 months, with 4 entries in 2024 (2024-04-01 through 2024-10-22) and 3 more in 2025 (2025-02-12 through 2025-06-05).

Frequently asked
What’s the largest disclosed funding amount in this privacy and security “Series Unknown” set, and how does it compare to other disclosed rounds?
StackHawk’s $12M on 2025-05-22 is the largest disclosed amount, and it is substantially above the next-largest disclosed round of $4M (Liberty Defense on 2024-08-22). The remaining disclosed floor is $500K (SafeGuard Privacy on 2023-12-12), while 8 of 10 entries list “undisclosed.”
Do any cities repeat enough to suggest a geographic cluster in these most recent entries?
Israel appears as a recurring geography in multiple entries—Noma in Herzliya/Tel Aviv on 2025-06-05 and Piiano in Tel Aviv on 2024-04-01—while most other entries are single-city U.S. placements (e.g., StackHawk in Denver on 2025-05-22 and SafeGuard Privacy in New York on 2023-12-12). No other city repeats across the rows shown.
Which entries fall in the most recent 90 days of the table’s latest round date?
Using the latest date shown (2025-06-05, Noma), the entries within roughly the prior 90 days are Noma (2025-06-05), StackHawk (2025-05-22), and Restrata (2025-02-12 does not fall within 90 days; it is outside that window). Only the first two are clearly inside the 90-day band based on the listed dates.
What does the stage/amount disclosure mix look like across these 10 rows?
All 10 entries are labeled “Series Unknown,” so the stage classification is uniform here. Disclosure is the variable: 8 of 10 rounds are “undisclosed,” with the three disclosed amounts spanning $500K (SafeGuard Privacy, 2023-12-12) through $12M (StackHawk, 2025-05-22).
Are there outliers in disclosed funding amounts or geography that stand out for follow-up?
The primary funding outlier is StackHawk’s $12M (2025-05-22), which is materially higher than the other disclosed amounts ($4M on 2024-08-22 and $500K on 2023-12-12). On geography, the list stands out for Israel being represented by at least two entries (Noma on 2025-06-05 and Piiano on 2024-04-01), whereas most other geographies appear once.
