We build what we couldn’t buy.

Symeon designs and builds software, infrastructure and the systems that connect them. Every product started as a problem we ran into ourselves and couldn’t solve properly with what was on the market.

Four disciplines behind everything we build

Good security software needs all four. Most teams have one or two. Ours have spent careers across every one of them, which is why our products handle the parts others gloss over.

Software engineering

Years building multi-tenant platforms that hold up under real use — and the operational detail that only shows itself once thousands of people depend on them.

  • Multi-tenant SaaS architecture
  • API design and systems integration
  • Data modelling at scale
  • Systems built to be maintained

Infrastructure

We run our own platforms rather than hand them to someone else. The unglamorous work — monitoring, failover, recovery — is work we do daily, not theory.

  • Cloud architecture and operations
  • Containerised deployment pipelines
  • Monitoring, alerting and observability
  • Backup, failover and tested recovery

Security

Not a compliance checkbox. We build against how attackers actually behave, because our products exist to train people to recognise exactly that.

  • Human-risk and social engineering
  • Security architecture and review
  • Authentication and access design
  • Threat modelling

Communications

Email, SMS and voice at volume. Deliverability, carrier routing and sender reputation are where most platforms quietly fail — so it’s where we went deep.

  • Email deliverability (SPF, DKIM, DMARC)
  • SMS via direct SMPP carrier connections
  • Programmable voice and IVR
  • Sender reputation and domain management

How we work

1

The brief is a real problem

Because each product began as something we needed, we already know what the edge cases are — and which shortcuts turn into support tickets eighteen months later.

2

We run what we ship

Our platforms are operated by the people who built them. When something breaks at 3am it’s our problem, which is a powerful incentive to build it properly first time.

3

Depth over surface

The hard parts — deliverability, carrier routing, realistic attack simulation — are exactly where competitors stop. They’re where we start.

PhishAware

Security-awareness training built the way we'd want it ourselves: realistic phishing simulation across email, SMS and voice, with training that assigns itself the moment someone slips.

It exists because the tools we kept meeting were running the same tired scenarios attackers abandoned years ago. PhishAware builds simulations against current threats, runs a full programme on autopilot, and turns each mistake into a teaching moment rather than a statistic. It’s our flagship product — and the clearest example of what the four disciplines above produce when they sit in one team.
