Dynamic Security Layers

Crossbeam is a partner ecosystem platform that helps companies build more valuable
partnerships by acting as an escrow service for data. The platform allows companies to findoverlapping customers and prospects with their partners – all while keeping their data privateand secure.
As a technology company that relies on maintaining data privacy, securing sensitive andproprietary customer data is at the forefront of organizational decisions. One of their corevalues is “Trust is Our Business”. With email being the most vulnerable attack vector used bycybercriminals to breach organizations and gain access to sensitive data, Crossbeam sought tofind an email security platform that can most effectively reduce risk to their users, organization,and customers.

Identification of Email Security Challenges
Chris Castaldo, a 20-year CISO and author of “Start-up Secure: Baking Cybersecurity into yourCompany from Founding to Exit,” is sought after by organizations that have a security-firstmindset and need to develop and implement a layered approach to cybersecurity. After joining
Crossbeam, Chris identified 3 cybersecurity projects that required immediate attention, includinga reassessment and maturation of their email security program.
As a cybersecurity veteran, Chris has developed a complete perspective of email security thatallows his security teams to address threats most effectively. Some organizations have the belief
that phishing can be prevented, automatically and without respect to the fundamental humanelement that phishing attacks rely upon. While obvious phishing attacks can be addressedwith native platform capabilities in some circumstances, Google Workspace (or Microsoft
O365 for those who use it) are considered the first line of defense to mitigate risk using static
security controls. But more sophisticated polymorphic attacks require adaptive controls andcompensating controls that manage risk without impacting an organization’s communication
capabilities. These advanced attacks, including business email compromise and vendor supply

chain impersonations, typically leverage an existing trusted relationship and are more difficult to simply block. To detect these threats,
Chris recognized the need to layer together dynamic email security controls to identify these risks and flag potential threats, andto engage Crossbeam’s users intelligently, with contextual phishing controls that would minimize risk without impacting their email
platform’s usability. Chris and his security team began assessing approaches used by email security vendors in their selection process.

Considerations for Email Security Vendors
Crossbeam has a small and nimble security team. The company required an easy-to-use solution, with best-in-class customer supportand deep security expertise, to improve the company’s security posture and reduce the inherent risk within email. Though businessemail compromise was a primary concern, ransomware and supply chain risks were also a top priority for the chosen email security
solution to detect and remediate, as 40% of ransomware attacks start through email.
Another key consideration in the selection criteria for the chosen email security vendor was having a seamless process acrossimplementation, on-boarding and the ongoing support to assist in the research and response of identified risks. Given a need for
efficiency within Crossbeam’s security team, the email security vendor needed to provide comprehensive support and experience, andthe ability to create customized risk-management policies tailored to Crossbeam’s user base, without
being hard to configure or requiring constant tuning and adjustment. And, with their security team’stime being stretched thin, communication between their team and the vendor needed to be effectiveand accurate.

Instant Results that Reduce Email Risk

"GreatHorn
quantifiably reduced
the risk of email by99%, based on how
many emails arequarantined versus
the number of userreported suspicious
emails."-Chris Castaldo,CISO, Crossbeam

Upon implementation of GreatHorn, Chris’s team experienced an immediate drop-off of businessemail compromise attacks that leverage trusted relationships, including “urgent task” requests thatoften bypass traditional email security vendors. And, during the Proof of Concept, they experienced
the ease-of-use and speed of setup, providing instant time to value for Crossbeam to quantitatively
report on their mitigated risks. “The very forward-leaning nature of the platform and capabilities
is imperative to the security posture at Crossbeam. There are so many things that GreatHorn has
the ability to prevent against, and other vendors simply aren’t addressing,” said Chris. And mostimportant to Crossbeam and Chris was that they quantifiably reduced the risk of email by 99%, basedon how many emails are quarantined versus the number of user-reported suspicious emails.
By incorporating GreatHorn’s Extended Monitoring services, Chris’s team was able to leverage
GreatHorn’s expertise with a dedicated Customer Success Manager who became an extension of
their team to manage the day-to-day activities and achieve the most comprehensive email security
posture. “It is such a value add and has been a seamless experience for us. We want the mostadvanced protection to adhere to our due diligence standards, but this can be time consuming.
When we compared hiring an engineer for $150k-$200k versus the Extended Monitoring offering, it’sa no brainer.”

The GreatHorn Cloud Email Security Platform has provided Crossbeam
with a valuable return on their investment and defensible security posturethey can count on.
