Tessian protects every business’s mission by securing the human layer 💫
We're building intelligent security that works for human beings as they are, not how security policies would like them to be. Using machine learning technology, Tessian automatically predicts and eliminates advanced threats on email caused by human error - like data exfiltration, accidental data loss, business email compromise and phishing attacks - with minimal disruption to employees' workflow. As a result, employees are empowered to do their best work, without security getting in their way.
Founded in 2013, Tessian is backed by renowned investors like Sequoia, Accel and Balderton and has hubs in San Francisco, Boston, and London.
Information Security at Tessian 🗝
We're looking for a hands-on Information Security leader to keep us growing increasingly secure, and consistently embed a security-first culture in all our Tessians. 
We believe security should work for everyone, with teams empowered and enabled to make – and want to make - good security decisions. We're fast paced and dynamic, and balancing agility, the nurture of security practice, with the accountability of being our InfoSec expert-in-residence, is at the heart of this role. 
Information Security crosses many functions, & there are thousands of signals telling us what we can do – theoretically, technically, legally – but we’ll be looking to you to advise us what we should do – and how. You'll be a prioritisation expert, and it'll be top of mind to have the biggest security impact with every move played.
Reporting to our CFO, you’ll have oversight of all our Tessian-wide information security practices. As a builder, you'll be ready to get us going from a standing start, and ownership and accountability will be at your very core. You'll be running solo, and own both the strategy and the implementation, and you’ll see your impact in every secure practice and every day that passes by, safe, enabled & secure.
For total transparency, we're hiring one headcount but have a few job descriptions open - we're open to either a Head-of or a CISO, and for this to be based in either the UK or US.

Some things you'll be involved in include:

  • Working closely with our teams to deliver the best possible product whilst meeting legal, regulatory, and customer expectations
  • Scaling Tessian’s InfoSec practices, creating self-serve frameworks to enable the business as much as possible, e.g. for application and process approvals
  • Getting gritty to ensure InfoSec sections of client DDQs are answered
  • Leading us through any incidents that may arise, & ensuring our disaster recovery strategy is tested & fit for purpose
  • Implementing, improving & running forwards procedures to ensure we maintain compliance with ISO27001 and GDPR
  • Working closely with Tessians across multiple continents, to ensure that information security is built into everything we do
  • Working with our Threat-Intelligence analyst, and liaising with the Marketing team, to tell our security thought leadership story
  • Designing controls to mitigate information and data security risks within the wider business
  • Identifying vulnerabilities in our practices and establishing improvements
  • Ensuring the confidentiality, integrity and availability of Tessian’s operations

We'd love to meet someone who:

  • Has a track record in a senior InfoSec role, and has a technical background
  • Loves a fast pace & a lot to do!
  • Can work in a multi-OS (MacOS, Windows, Linux) environment
  • Is willing to get stuck in at all levels, from hands-on implementation through to strategy
  • Is up for a debate with our most senior stakeholders
  • Has an inquisitive mind, and doesn’t take things at face value
  • Is comfortable with an ever-changing landscape
  • Believes the job is never finished but..
  • Doesn’t hold back from shipping something better, fast, & often
  • Is solution-oriented, and can chart a path through muddled waters
  • Is dedicated to security, but knows ‘process’ isn’t always the answer
