Tessian protects every business’s mission by securing the human layer
The Tessian Cloud Email Security platform helps enterprises defend against email attacks, protect against data loss and respond to security incidents more efficiently. By combining artificial intelligence with an understanding of employee email behavior, Tessian is able to prevent complex email attacks and data loss incidents that evade Secure Email Gateways and the built in security controls of M365 and Google Workspace.
The world's largest banks, healthcare organizations, hedge funds and law firms all use Tessian to secure their email environments, data and people whilst saving their security team time. In 2022 alone, Tessian prevented hundreds of thousands of business email compromise attacks, data loss incidents and saved hundreds of hours of work for security teams.
Tessian is headquartered in London and Boston with 200+ employees globally and has raised over $120m in venture capital funding from world leading investors like Sequoia, Accel, Balderton, March, Citi and Okta. Tessian was recognized as one of Fast Company’s Most Innovative Companies for 2022. More information can be found at www.tessian.com.
Data / Threat Analysis at Tessian
As a high-growth scale-up, our email datasets are growing at an exponential rate. This is a great problem to have as it allows us to train best-in-class machine learning models to prevent previously unpreventable data breaches. We have scaled to the point where there are so many emails flowing through our system that need more human eyes to understand some more advanced patterns and feed them back into our algorithms.
You will lead our Threat Intelligence team and work day-to-day with Threat Analysts, Data Scientists and Engineers to build out the flow of identifying any weak points in our algorithms and coming up with ways - in collaboration with our data scientists - to detect these types of emails. You will also work with Sales Engineers, identifying a better flow to surface the value of what Tessian does to our customers, which requires you to deeply understand the product and the way our customers benefit from it.
We view this role as a hugely impactful, high-leverage role and strongly believe that if we can have a smooth and robust feedback flow from incoming emails to outgoing ideas that we can deliver more value to our clients through the data breaches we prevent. In this role you should be a spokesperson both internally and externally in the Threat Intelligence landscape.
Some interesting projects we’re working on:
Building an advanced threat intelligence infrastructure
Training and Deploying advanced ML models on a combination of structured and unstructured (NLP) data.
Improving the deployment flow of algorithm changes to decrease time from idea to production
Automating reporting to surface product value to our customers
Designing the next generation data-lake setting ourselves up to handle massive future scale
Responsibilities:
Look at advanced email attacks and understand the underlying tactics used to try to bypass our systems
Label these emails to their correct categories to help the Algorithm teams to improve their ML Models
Take insights from these emails and leveraging our threat intelligence infrastructure to block similar threats in the future
Surfacing these ideas back to the Data Scientists so they can deploy more robust ways of blocking these tactics
Presenting to the wider company about threats we’re seeing to keep them informed
Taking calls with customers using our product to understand and surface the value of Tessian
Improving the tooling for reporting this value back to customers
Writing blog posts about new and emerging threats
Qualifications:
Have basic+ Python knowledge and the ability to look at datasets in Python
Have a real hunger for learning and pushing Threat Intelligence around Email Security to the next level
Ideally have experience in the email security field
Ideally have some experience with Machine Learning systems
Has an ability to break down ambiguous problems into concrete, manageable components and think through optimal solutions
