Security
Expert-driven. Tool-assisted.
We dive deep into an application. Its uses, business context, and technology stack.
We understand its users — and its attackers.
We provide concrete insights to strengthen the application against real-world threats.

Methodology
Automated analysis can reveal a lot about a application’s security posture. A rule-based static code scan or an AI-backed dynamic review of a deployed product can be incredibly beneficial.
But relying exclusively on automation lacks core aspects of real cyber-attacks — human motivation, persistence and ingenuity — and may even do harm by misguiding application engineers with surface-level security findings.
When a user interacts with a product, they have a reason for using it, a goal to accomplish.
When someone with a hacker’s intuition — possibly malicious — interacts with the same system, they spot how users may use, misuse or abuse the system’s features.
This understanding contextualizes product vulnerabilities. For example, chaining a few low-impact security issues may be the stepping stone that gives an attacker access to the valuables they are after.
SealSec’s security projects are led by a security expert with a hacker’s mindset, who takes time to understand an application’s use cases, its users, and its attackers.
This is what we call a security deep dive, and it sums up SealSec’s core security philosophy and methodology:
- A security engagement is expert-driven and requires an in-depth understanding of not just technical aspects of an application, but human aspects too — its business goals and constraints, its users, and its real-world threats.
- Security is a collaborative effort. Vulnerabilities can and should be explained in clear, simple terms. Clients and developers are involved throughout project execution.

Web
The digital world is largely built on a backbone of web APIs. From mobile payments to AI model queries, client-server communication often takes place using an HTTP-based protocol.
A breach of the API backend used by your product's front-end constitutes a scalable — and for attackers a highly attractive — attack vector.
Mobile
By a large margin, mobile devices are how people use applications — from gaming to banking to digital ID.
Yet they are often treated as toys, rather than sophisticated computers that require careful handling and deliberate securing.
Does your mobile product offer enough security assurance on these untrusted platforms?
Gaming
Much of our time and money is spent in simulated worlds and communities: games.
Modern anti-cheat relies on client-side protections and device attestation. But to drastically increase attack complexity and reduce attack success rates, a game must also employ a well-tuned server-side attack detection model.
Infra & Cloud
An often-overlooked aspect of application security is its underlying infrastructure. This typically involves a microservice deployment in the cloud, e.g., on Azure, AWS or GCP.
By identifying identity and access flaws, insecure deployment configurations and DevOps pipelines, different vulnerability classes can be avoided — or their impact reduced.
Reporting
A security assessment typically uncovers a number of security weaknesses. Identified weaknesses and recommended improvements are clearly described in a report.
Additionally, the report includes an executive summary and outlines a straightforward roadmap to mitigate the identified vulnerabilities.
Consulting
After delivery of the security report, SealSec is available for folllow-up security improvement consultation.
Consultation is tailored to the client's business needs and aimed at remediating the identified security gaps.

Impact of cybercrime
The impact of crime in the "real" world is often directly visible.
What do we know about the human impact of cybercrime?
This post explores recent research (Borwell, 2025).
AI-assisted attackers
We may choose to ignore or deny AI — but malicious actors don't.
Attacker skill scales, almost for free, with increased quality of large language model-based tooling.
A new AI feature of the industry-standard HTTP proxy, BurpSuite, is explored in this post.
Game economies
Videogames are simulated worlds with, to varying degrees, real economies.
In this post, a deep dive into the security resilience of the economy of an old game — with special focus on how players perceive (or construct) in-game value.
