With venture capital flowing into the cybersecurity space at a record level, investors continue to hunt for the next big thing.

In the last two months, that has meant looking at how applications talk to each other — and how to protect the data and services that flow through them between application programming interfaces, or APIs as they are more commonly called.
“We get multiple emails a week from investors sniffing around,” said Larry Link, CEO of Sunnyvale, California-based API security provider シーケンスセキュリティ. “We see interest from PE, from growth venture — they all want to play in this space.”
That is not the only round API security providers saw in the last several weeks. Last month, London-based 42Crunch raised a $17 million Series A. Later that month, Palo Alto, California-based 塩のセキュリティ 閉じた 70万ドルのシリーズC — raising the total amount of funding the company has seen in the last year to $120 million. Earlier this month, Colorado-based ThreatX announced it had closed a $10 million round.
The rise of APIs
An API is what enables two applications to talk with each other. For example, when you look up cheap flights on the Internet, the app you are using needs to connect to the databases of airlines to see what may be available. That connection is through an API.
“The API discussion is part of every discussion we have,” said ThreatX CEO Gene Fay. “Every company is leveraging more and more APIs.”
The proliferation of APIs is in large part due to the growth of “microservices,” Link said. Microservices is a style of building apps by loosely coupling services around the application’s main business function. As companies build their apps, developers integrate it with providers of microservices — things like communication, logistics and login verification. As more of these microservices become available, developers add them to apps through APIs.
“Companies really have no idea what their API footprint is anymore,” he added.
Just this year, huge companies such as ペロトン, クラブハウス, エクスペリアン ジョン·ディアー have run into API security incidents. Fay said his company noticed a multiple-fold increase in API attacks from the second quarter of last year — as cyber attackers used the pandemic to hone their skills — to the second quarter of this one.
Without secure APIs to protect the data and services that flow between applications, bad actors can take over accounts or disrupt a company’s ecommerce business.
“I am seeing an increase in companies that know their APIs are exposed,” Link added.
Still early innings
Although API security recently has captured investors’ imaginations, it still is a nascent space when compared to other areas of cybersecurity. According to Crunchbase data, companies that describe themselves as securing APIs only have seen about $193.4 million of venture funding in the last 18 months — most of that going to Salt Security — although that is more than triple what the space realized in 2018 and 2019 combined.
Dracon compares the API security to what endpoint security was several years ago. As actors became more sophisticated, antivirus tools from シマンテック マカフィー began to lag. That gave rise to companies such as カーボンブラック, 群衆 Cylance, all of which became large companies before exiting to the public markets or being acquired.
The application space is seeing much more modern, advanced attacks and the API has become a common attack vector. With that trend, next-generation application security is needed, Dracon said.
Aside from the recent funding rounds, the API security space has also witnessed some dealmaking. Just last month cyber giant Imperva社 bought Los Altos, California-based API security developer CloudVector 公表されていない金額。
“I expect all large cyber vendors will have a play in this space at some point,” Dracon said.
“Those guys are interested in the API space,” said Link, who expects to raise a $40-to-$50 million Series C growth round by the end of the year.
Fay added he expects the market evolution in the next three-to-four years will determine the ultimate winners.
“This space continues to get recognized …. And I know there are companies that will come into it,” Fay said. “I think there is a ton of market opportunity out there as this market grows.”
