  • Why it’s great news that cyber insurance is becoming more popular

“It’s not really in our nature to love competition. In fact, it’s complete animal instinct to want there to be no competition at all. This applies to business, relationships and basically every other form of human interaction. Nobody wants to compete. So you can imagine how a growth in businesses taking out cyber insurance (and therefore business insurance) could be a little concerning to certain people in the digital sphere.”

What is the Role of Cybersecurity in your Enterprise?

What does cybersecurity mean to your business? This might seem like an odd question, but how an enterprise responds to it can say a lot about the culture and practice of cybersecurity within that organization. There are many different ways to ask the same question — Which function does cybersecurity report to within the enterprise? Who are the internal clients of cybersecurity? Does cybersecurity leadership have a voice at the highest levels of corporate decision-making? There are 2 main schools of thought about the role and orientation of cybersecurity within the enterprise. The traditional school places cybersecurity within the Information Technology (IT) function of a business. In this model cybersecurity reports to IT, IT is the internal client for cybersecurity, and the CISO might report up to the CTO or CIO. It’s easy to see why one might make this association. IT and cybersecurity professionals often have similar or adjacent skillsets and overlapping educational and professional backgrounds. Both functions often deal with highly technical, specialized, and complex information and processes. However, the goals and KPIs of IT and cybersecurity are not only unaligned, they are often in direct conflict. The internal clients for IT are other business functions that essentially pay for the various technology assets (applications, servers, cloud instances, etc.) required to keep the enterprise running. IT performance is evaluated by how seamlessly, continuously, and cheaply they are able to deliver their services. IT doesn’t really have visibility into or an understanding of how these assets are being used by the business, what kind of data they process, which critical business functions they support. When cybersecurity comes to IT and tells them that a particular technology asset or part of the IT infrastructure has problems or weaknesses that could be exploited by malicious actors, they have to weigh the benefits — stopping a potential attack that may or may not happen vs. the costs — resources allocated to fix the problem, unhappy internal clients due to technology assets being unavailable during fixing, valuable time spent fixing and validating the issue. This is a hard sell and essentially amounts to self-regulation. A significant percentage of breaches exploit known vulnerabilities and weaknesses within an organization. Looked at from this lens, it's not difficult to see how such problems can go unaddressed. The modern school of thought recognizes Cybersecurity as its own independent vertical within the enterprise — like sales, marketing, HR, or any other function whose purpose is to help the business function and thrive. In this model, cybersecurity has various different business functions as internal clients, and the CISO might have a seat at the C-level table. Cybersecurity informs business stakeholders of the risks they face as a result of the technology infrastructure they utilize. The business stakeholders provide the context necessary for informed risk triage and collaborate with cybersecurity to identify which vulnerabilities or weaknesses pose the biggest threats to the part of business they own. These prioritized risks are then sent to IT for remediation. Cybersecurity provides guidance to IT on how they may remediate or mitigate a particular problem. Since risk remediation or mitigation is being driven by the business stakeholders, IT is incentivized to fix these problems. Risk-based cybersecurity is a methodology for program design that can help organizations put this modern approach into practice. By putting an emphasis on incorporating business context in the risk analysis process and data models, and by ensuring that business stakeholders are involved in the decision chain, risk-based cybersecurity programs provide a shared space where IT, business, and cybersecurity can come together and collaborate.

Brinqa Growth and Future

I'm proud and excited to announce that Brinqa has raised $110 Million in growth capital from leading global venture capital and private equity firm Insight Partners. This is our first institutional investment and represents a significant milestone for the company. Brinqa was bootstrapped and remained founder-backed as we shaped the Cyber Risk Management space, achieved strong organic growth and profitability, and acquired some of the biggest brand names in the world as customers. This new injection of funds combined with Insight Partners' ScaleUp expertise will fuel the next stage of our growth and accelerate ongoing efforts to make Brinqa an essential, unifying component of every enterprise cybersecurity ecosystem. Our mission, values, and objectives as a company remain the same; this partnership will help us achieve them faster and better. We decided to take this step with Insight Partners because of how aligned they are with our vision for Brinqa and the priority of long-term and short-term goals. We firmly believe that Brinqa is an essential platform for all enterprise cybersecurity organizations. As digital transformation proliferates across industries and saturates every aspect of business, the IT infrastructure to enable and the security ecosystem to protect become larger and more complex. Imagine a scenario where hundreds of different teams, systems, and programs — each focused on a task so demanding and technical that it requires specialized skills and tools — work towards the same overarching goal but rarely communicate with each other. Unfortunately, this is often the reality for most cybersecurity organizations. To be effective and a true contributor to business success, it must function as ONE TEAM aligned in purpose, connected in data, and transparent in communication. This is the vision that Brinqa helps our customers achieve. We know that this is possible because we have proven it at some of the world's largest and most complex enterprise IT environments. We are fortunate to count among our customers three out of the five largest retail companies in the world, the largest healthcare providers in the US, and the most prominent global brands in technology, financial services, insurance, healthcare, manufacturing, aviation, and critical infrastructure. This partnership will help us bring this vision to cybersecurity practitioners and organizations everywhere. The capital infusion will be used to accelerate sales and marketing initiatives, enhance customer experience and community building, and strengthen partner and channel ecosystems. I am so thankful to the Brinqa family — our employees, customers, and partners. You are the source of the immeasurable hard work, innovation, creativity, and conviction it has taken to reach this huge milestone, and all credit for this accomplishment goes to you. I am excited as we embark on this next stage of our journey and look forward to achieving greater heights together.
