DDoS Protection for Travel Platforms: Lessons from Peak Booking Season

Fri, 29 May 2026 00:00:00 +0000

Travel platforms have a DDoS problem that most other industries don’t. Attacks aren’t more frequent than elsewhere (though they are during peak periods). The harder thing is that the threat environment and the normal operating environment look almost identical from a traffic perspective.

Black Friday for ecommerce is a known spike on a known date. You scale up, you brace, you monitor. But a travel platform’s “Black Friday” is an airline announcing a flash sale at 11pm on a Tuesday. Or a popular travel influencer posting a destination recommendation that sends 400,000 people to your site inside 90 minutes. Or school holidays hitting five countries simultaneously across your booking engine.

API Security in Ecommerce: What CTOs Get Wrong

Tue, 26 May 2026 00:00:00 +0000

Most ecommerce CTOs we talk to have a reasonable handle on their frontend security posture. WAF in place, DDoS protection sorted, bot management on the roadmap. The conversation gets uncomfortable when it turns to APIs.

It’s not that they’re unaware. They know APIs need securing. The attack surface is just bigger than it looks, the tooling caught up later than it did on the web application side, and most API programmes have gaps nobody’s had time to close. Then on top of that, AI shopping agents have started hitting ecommerce APIs in volume over the last year, and that has changed what “normal” traffic even means.

How Page Latency Kills Ecommerce Revenue in 2026 (And How to Fix It)

Fri, 22 May 2026 00:00:00 +0000

Speed is not a feature. It is revenue.

That framing still surprises some CTOs when we use it in a first meeting. Performance has traditionally lived in the engineering team, treated as a quality metric or a technical concern, something you optimise when you have spare sprint capacity. Finance does not talk about it. The board does not ask about it. It does not appear on the P&L.

Except it does. It appears indirectly, in conversion rates, in average order value, in cart abandonment, in paid acquisition efficiency. And the relationship between milliseconds and money is well-documented enough at this point that treating performance as a secondary concern is, plainly, a commercial mistake.

How Bot Attacks Drain Fintech Revenue — And How to Stop Them

Tue, 19 May 2026 00:00:00 +0000

Bots now account for nearly half of all internet traffic. But not all bots are created equal — and the ones targeting your fintech platform aren’t browsing. They’re working.

They’re testing stolen card numbers against your payment API. They’re taking over customer accounts. They’re scraping your pricing data. They’re stuffing credentials until one works. And while they do it, they’re quietly draining your revenue, degrading your infrastructure performance, and eroding the trust your customers place in you.

Digital bank: securing an API estate they didn't know they had

Sun, 10 May 2026 00:00:00 +0000

The challenge

Four years into operation, the bank had grown fast. Microservices, third-party integrations, multiple mobile app versions, open banking connectors. Engineering shipped constantly and the API estate accumulated with it. Ahead of a DORA compliance review, the security team wanted to establish what their actual API surface looked like before the regulator did.

The answer was uncomfortable. They thought they had around 300 API endpoints. We found 441.

Around 140 additional endpoints: old API versions never decommissioned, internal services exposed externally during development and never pulled back, integration endpoints from partnerships that had since ended. Six had no authentication requirement at all. One of them returned customer transaction history without an auth header.

Why most microsegmentation projects stall — and how to avoid it

Wed, 22 Apr 2026 00:00:00 +0000

Microsegmentation has a reputation as one of the highest-leverage controls a modern security team can deploy — and also as one of the most likely to get stuck. We’ve seen the same pattern dozens of times.

A team buys a microsegmentation platform after a ransomware scare, a compliance audit, or a Zero Trust mandate from above. Agents get installed, the discovery phase produces a beautiful dependency map, and then… nothing. Six months later, the platform is still running in observation mode, no enforcement policies have been pushed live, and the project is quietly sliding off the roadmap.

Hotel group: shutting down credential stuffing on a loyalty programme

Fri, 10 Apr 2026 00:00:00 +0000

The challenge

The client runs a loyalty programme across a group of mid-market hotels in Europe. Members accumulate points on stays and redeem them for free nights and room upgrades, or transfer them to airline frequent flyer programmes. Several million registered accounts, active enough that points have real monetary value to members and, it turned out, to attackers.

The fraud team spotted it first. An unusual volume of points-to-miles conversion requests, all routing to the same small set of airline frequent flyer numbers. The accounts initiating the transfers looked normal: real members, real historical activity, real email addresses. Just not the real owners converting them.

European challenger bank: PCI DSS at the edge, zero outages in two years

Wed, 08 Apr 2026 00:00:00 +0000

The challenge

A fast-growing European challenger bank had outgrown its initial cloud-native architecture. With customer count tripling year-over-year and increasing scrutiny from financial regulators, the platform needed:

A PCI DSS Level 1 Service Provider ready edge architecture
Sub-200ms TTFB across Europe
A serious answer to DDoS and credential stuffing
Workload-level isolation for cardholder data environments

The existing stack — a single-region cloud provider’s WAF and CDN combination — couldn’t deliver any of these at the required level.

Bot management isn't a checkbox — it's a tuning practice

Wed, 18 Mar 2026 00:00:00 +0000

Bot management is one of those product categories where the marketing makes it sound like a turnkey product. Buy the platform, flip it on, the bots disappear. In reality, every bot management deployment we’ve inherited from a “turn it on and forget it” approach has been measurably underperforming — sometimes spectacularly.

Why generic defaults fail

The vendors aren’t lying when they say their products work out of the box. They do — for a generic web application. The problem is that no real application is generic.

Fashion retailer: stopping SMS pumping before it became a $500k problem

Thu, 05 Mar 2026 00:00:00 +0000

The challenge

The client is a mid-market fashion retailer with a European customer base. Customers log in with their phone number and receive a one-time code by SMS — no password, OTP is the authentication. Normal SMS volume ran around 50,000 messages per month. Predictable cost.

At 3am on a Tuesday, the login flow stopped working. Their SMS gateway had suspended the account for unusual traffic. The attack had been running four hours.

The CDN math that actually matters for e-commerce

Tue, 10 Feb 2026 00:00:00 +0000

When we audit a CDN deployment for an e-commerce client, we don’t start with the dashboard the vendor provides. We start with four numbers. If these four numbers aren’t being tracked, optimized, and reported every month, the deployment is almost certainly underperforming.

1. Cache hit ratio (by content type)

The aggregate cache hit ratio is mostly useless — it’s dominated by static assets that would cache anywhere. What matters is the cache hit ratio broken down by content type:

Global retailer: Black Friday-ready in 90 days

Thu, 15 Jan 2026 00:00:00 +0000

The challenge

A top-100 global retailer had spent two years quietly outgrowing its existing CDN deployment. With a major Black Friday campaign 90 days out, the team flagged two problems they couldn’t solve internally:

Catalog cache hit ratio was 71% — and origin egress was scaling alarmingly with traffic
Scraper traffic from competitors had reached an estimated 18% of total catalog requests
Previous peak seasons had required emergency origin scaling and triggered Tier-2 incidents

The platform team needed a 90-day path to confident peak readiness.

Merry Christmas and Happy New Year from Eknix

Tue, 23 Dec 2025 00:00:00 +0000

The best kind of holiday is one where nothing goes down — and we hope yours is exactly that: quiet, warm, and uninterrupted.

Thank you for a year of building good things together. We’re grateful for the trust you place in us and genuinely excited about what’s ahead.

Wishing you and your team a restful Christmas and a new year with 100% uptime where it counts.

Regional airline: cutting search latency in half, globally

Sun, 30 Nov 2025 00:00:00 +0000

The challenge

A regional airline group with operations across three continents was losing competitive ground in metasearch placement — primarily because their search response times were too slow. Internal data showed look-to-book ratio dropping below industry benchmark in three key markets.

The technical root cause was a series of inefficient paths between metasearch partners, the airline’s booking API, and downstream GDS calls. Each hop added latency, and the existing CDN deployment wasn’t optimized for the request patterns.

How CDN node mapping actually works

Mon, 10 Nov 2025 00:00:00 +0000

There’s an interview question that used to be a rite of passage in backend engineering: “Walk me through everything that happens when a user types a URL and hits enter.” Most answers got stuck on DNS and TLS. The part most people glossed over — how the request actually lands on the right CDN node out of thousands distributed globally — is where the interesting engineering lives.

Get the mapping wrong and your users in Singapore are hitting a PoP in Frankfurt. The latency shows up in your P75 TTFB, in your bounce rate, and eventually in your revenue numbers.

Why CDN Vendors Hide Their Prices (And What to Do About It)

Wed, 10 Sep 2025 00:00:00 +0000

You’ve spent hours comparing solutions. One site finally looks right. You want to know what it costs. And instead of a number, you get a button: “Contact Sales.”

If that’s felt like a wall, you’re not alone. But having been on both sides of that conversation — as a buyer evaluating CDN options and as a practitioner who’s helped clients negotiate enterprise contracts — I can tell you the button isn’t evasion. It reflects something real about how these products are built and sold. Understanding the logic makes the process a lot less frustrating.

CDN to Origin Certificates: Your Own CA with OpenSSL

Tue, 15 Jul 2025 00:00:00 +0000

There’s a common assumption that because a CDN handles the TLS connection your users see — the certificate shown in the browser’s address bar — you don’t need to think too hard about certificates on your origin. That’s wrong, and the consequences show up as cryptic error codes rather than obvious failures.

A CDN like Akamai doesn’t act as a transparent tunnel. It terminates the TLS session from the client, inspects and processes the request, then opens a new TLS session toward your origin. Two separate connections, two separate certificate validations.

Is Google reCAPTCHA a DDoS Defence? The Cost Math Says No

Wed, 14 May 2025 00:00:00 +0000

There’s a category of question that gets asked quietly in Slack channels and in private post-incident reviews: “could we just use reCAPTCHA to handle this?” It’s not an unreasonable instinct. Google reCAPTCHA is already deployed on most sites, it can challenge suspicious traffic, and it costs nothing for the first ten thousand requests. As a lightweight speed bump, it has its place.

But “speed bump against DDoS traffic” and “speed bump against spam submissions” are very different things — and running reCAPTCHA into a volumetric attack has a financial profile that most teams haven’t priced out before they need to.

Do You Know How Your Customers Experience Your Site? Or Just Where They Go?

Thu, 10 Apr 2025 00:00:00 +0000

Most engineering teams I talk to have Google Analytics. A lot of them assume that means they understand how their site is performing. It doesn’t.

Google Analytics is an excellent tool for answering one set of questions: where do users come from, where do they go, what do they convert on, where do they drop off? It’s a behavioural map. It tells you the path. What it doesn’t tell you is what the path felt like — how long it took, how it degraded under load, which users are bouncing not because the content is wrong but because the page took five seconds to load on a 4G connection in Germany.

Happy New Year and Merry Christmas from Eknix

Mon, 23 Dec 2024 00:00:00 +0000

With the holiday season here, we wanted to take a moment to say thank you — genuinely — for being with us this year.

To every client and partner who trusted us with their platforms in 2024: it means more than we can say. Building good things together is what drives this team, and the work we’ve done this year has been some of our best.

Is Your Website Ready for the Holiday Rush?

Tue, 03 Dec 2024 00:00:00 +0000

11.11 just happened. Black Friday is right behind it. Then Christmas, then New Year’s. If your platform survived Singles Day with headroom to spare, you might be tempted to relax. Don’t. Each of these events amplifies the same underlying gaps — and the ones that don’t show up under moderate traffic tend to surface spectacularly under peak load.

The preparation conversation usually focuses on infrastructure scaling: more instances, higher database connection limits, load balancer tuning. That’s necessary but not sufficient. Two factors that consistently determine whether a platform has a good or bad holiday season sit outside the application layer entirely: security posture and edge performance.
