Curtail raises £2.4m in series seed funding

Curtail, a Santa Barbara, California based network traffic analysis solution and continuous security tool provider, announced on Tuesday (April.16th), via a press release on PRNewswire, that it has raised $3.25m (£2.4m) in funding, led by Tarus Capital along with other investors.

The new financing will be used to help build the company, particularly the engineering, sales, and marketing teams and initiatives.

According to the release, Curtail is changing the way IT is implemented for government agencies, financial institutions, service providers and enterprise organisations that are developing and releasing new software and services for DevOps and cloud environments.


Curtail network traffic analysis solution tool, Regrade, which allows consumers to release software updates with high-quality, enables software and DevOps teams to:

  • “Verify the quality of software upgrades and patches by using real production traffic.”
  • “Prevent costly rollback and cumbersome staging.”
  • “Regression test in development, quality assurance and production using breakthrough network traffic comparison analysis.”
  • “compare open source alternatives to achieve best application performance and security.”
  • “Quickly report on software and web services differences including content, metadata, and application behaviour and performance.”


Curtail’s continuous security tool, ReCover, will also be used to help teams to mitigate zero-day exploits and prevent server infrastructures from being accessed without the proper authority.

Recover will also isolate compromised servers without the risk of downtime and “negate false positive by switching traffic over to clean systems, eliminating the blocking legitimate traffic.”

“Traditional tools to find bugs in code are outdated in today’s rapid DevOps cycle times. While flaws in software can also be exploited by attacks, it’s most often the risk of unplanned downtime that causes the bigger risk for DevOps teams. It costs four to five times as much to fix a software bug after release, rather than during the design process,” said Frank Huerta, CEO of Curtail.

“System downtime is the enemy of every business. Despite the risks of unplanned downtime, many organizations that develop software and services often push them live without knowing how the software will perform against production traffic, said Chris Kane, partner of Tarus Capital.

“The industry needs new software testing methods to keep up with rapid DevOps cycles. Curtail’s approach is a game changer – helping customers to develop stronger applications and to eliminate the risks of software update differences and defects that impact quality as well as application security,” he added.
