LLM Penetration Testing: 2026 Methodology Guide

Sat, 02 May 2026 13:00:00 +0000

LLM penetration testing is not a normal web-app pentest with a chatbot bolted on. The attack surface includes the prompt layer, model behaviour, retrieval (RAG), tool and agent invocation, and output handling — and the most damaging failures usually live in the seams between those layers.

Kubernetes Pentest in 2026: What It Actually Covers

Mon, 20 Apr 2026 10:00:00 +0000

A Kubernetes pentest is not a network pentest with YAML on top. It is a different engagement — different scope, different assumptions, different attacker model — and by 2026 that difference matters more than ever.

The CNCF’s 2026 cloud-native survey reports that 82% of container users now run Kubernetes in production, up from 66% in 2023. Red Hat’s 2024 State of Kubernetes Security found that 89% of organizations had at least one container or Kubernetes security incident in the preceding twelve months, and 46% of them lost revenue or customers as a result. Wiz’s 2025 Kubernetes Security Report puts the speed of opportunistic attacks in stark terms: a newly provisioned AKS cluster sees its first attack attempt within 18 minutes; EKS within 28.

Mobile App Security Testing: iOS and Android Pentest Guide

Mon, 23 Mar 2026 09:00:00 +0000

Your mobile app runs on devices you don’t control, in environments you can’t predict. That binary sitting on a user’s phone — with its local storage, hardcoded configuration, and network calls — is an entirely different attack surface from your web application. It demands a different testing approach.

Penetration Testing Cost in 2026: $4K–$100K+ Guide

Tue, 17 Mar 2026 09:00:00 +0000

If you’re searching for “how much does a penetration test cost,” you want numbers — not vague marketing. Here’s the direct answer: most penetration tests cost between $4,000 and $25,000, with complex enterprise engagements reaching $100,000 or more. But that range is meaningless without understanding what drives the price.

Cloud Penetration Testing: AWS, Azure & GCP Security Assessment

Thu, 19 Feb 2026 16:40:30 +0000

Migrating to the cloud does not eliminate security risk — it transforms it. AWS, Azure, and GCP handle infrastructure-level protections, but the responsibility for securing configurations, identities, data, and workloads still falls on your organisation.

Cloud penetration testing is a controlled security assessment that simulates real-world attacks against your cloud environment. Unlike automated scanning, a cloud pentest uses manual techniques to chain together misconfigurations, overly permissive IAM policies, and exposed services into attack paths that actually compromise data.

Black Box vs White Box vs Grey Box Pentest

Fri, 23 Jan 2026 15:36:12 +0000

What’s the difference between black box, white box, and grey box penetration testing? If you think it’s about access levels, you’re wrong—and you’re not alone.

Most cybersecurity professionals, vendors, and even some pentest firms get this fundamentally wrong. The confusion costs companies money, weakens security assessments, and leads to compliance issues.

API Security Testing: OWASP API Top 10 Walkthrough

Wed, 14 Jan 2026 21:56:37 +0000

Introduction

APIs (Application Programming Interfaces) have become the backbone of modern software architecture. From mobile apps to microservices, organisations rely on APIs to connect systems, share data, and deliver functionality. But this connectivity comes with risk.

In 2026, APIs represent one of the most common attack vectors in web applications. According to industry data, 57% of organisations experienced an API-related data breach in the past year, with 73% of those facing three or more separate incidents. Major breaches continue to be traced back to insecure API endpoints.

TLPT: Threat Led Penetration Testing Explained

Fri, 20 Jun 2025 10:00:00 +0000

Threat Led Penetration Testing (TLPT), also known as threat-led pentesting, is the gold standard for realistic cybersecurity validation. TLPT combines the latest threat intelligence, red teaming tactics, and business risk analysis to simulate attacks that your organization is most likely to face. Unlike generic pentesting, TLPT tests not just your systems for vulnerabilities, but also your ability to detect, respond to, and contain those attacks in real time.

How to Choose a Penetration Testing Company?

Wed, 29 Sep 2021 07:57:12 +0000

Today is a time of frequent data breaches, automated hacking systems, and all types of consumer protection regulations like DSS, PCI, and GDPR. Because of this, penetration testing is now considered an essential security requirement for all types and sizes of businesses, not just governments and banks.

Penetration Testing Grows Due to Remote Work

Tue, 13 Apr 2021 18:16:48 +0000

Cybersecurity professionals are requested to conduct more penetration testing and security assessments focusing on remote work during the COVID-19 pandemic than ever before.

With the rapid transition to work from home during the COVID-19 pandemic, the organizations’ attack surface has evolved, and security measures could not remain unchanged. Businesses that care about their cybersecurity have shifted priorities to protect their network infrastructure, focusing on the growing risks of remote work, with pentesting as the means of immediate improvement.

Remote Work Security Audit – a Need or a Habit?

Tue, 10 Nov 2020 09:00:00 +0000

A year ago, before the COVID-19 pandemic, probably very few people could imagine how the world would change. Working from home, remote business meetings, online events, and digital concerts are only some new normal examples. The things we could not imagine going virtual very much did, to everyone’s surprise. One of the areas that tended to be very onsite and face-to-face was conducting a security audit – remote work security assessment.
