Mirroring Sun Tzu’s wisdom, “To know your enemy, you must become your enemy,” today’s cybersecurity landscape demands that security teams see their IT infrastructure through attackers’ eyes. This proactive approach is vital, notably considering the Data Breach Investigations Report (DBIR) finding that 65% of data breaches stem from external sources.
Adopting an attacker mindset enables security teams to identify and address attack vectors early and continuously manage their attack surfaces. This strategy entails asking questions like, “What assets can threat actors see and use as entry points?” and “How can compromising these assets impact other assets?”
It’s almost the end of an era in advertising. Google has started phasing out third-party cookies, beginning with 1% of Chrome users in January 2024. It plans to do the same for all users by the second half of the year through the Privacy Sandbox initiative.
To recall, Google’s Privacy Sandbox is a set of proposals for creating new standards for online privacy. The core idea is to develop methods for websites and advertisers to access user information for things like advertising and content recommendations without compromising user privacy. Among its key goals? Phasing out third-party cookies.
IPv6 became the Internet Standard Internet Protocol (IP) in July 2017, positioned to replace the fast-depleting IPv4. In this post, we’ll answer common questions about IPv4 and IPv6 addresses.
Knowing how to geolocate the IP address of a visitor or customer makes it easier for businesses to plan for strategic and tactical operations (e.g., reaching out to target audiences, setting up new offices and stores, promoting new products, gaining momentum, etc.).
Location is a crucial element when interacting with clients and prospects, and it should not only be considered by brick-and-mortar organizations but also online stores whose buyers are scattered all over the Web.
So, how can businesses geolocate IP addresses and get their hands on critical customer information? They can tap an IP geolocation database, a resource that enables organizations to obtain location-based data quickly and, as a result, get to know where their consumers are.
In this guide, we’ll find out how employing IP geolocation can benefit companies and what its most prominent use cases are across industries.
There are two common ways to configure deny lists for Nginx:
Personalization is the way to go when it comes to targeted marketing and advertising. Customers, existing and potential alike, want to feel that the brands they support care about their needs and try to predict what they might want. That’s what makes IP address research critical for digital marketers and advertisers.
But they aren’t the only ones who can benefit from IP geolocation data, cybersecurity pros, fraud protection agents, and market researchers do, too. Every computer or mobile device, after all, has a designated IP address that helps today’s companies and individuals pinpoint where their strongest markets are, identify where threats likely come from, detect potentially fraudulent transactions, and predict consumption patterns and trends.
Maximizing the profit is the ultimate goal of every business—and there are several ways to achieve that. For instance, you can reduce your expenses and product costs or increase your product or service prices. But generally, these strategies should be accompanied by techniques that seek to increase sales and find new customers too.
There are existing technologies in the digital world that can help you meet your business goals, and IP geolocation is one of them. In a nutshell, geolocation is the process of identifying the physical location of online users.
Whether intentional or not, businesses with an online presence—that is to say, almost all businesses have become global. Right now, people from any part of the world could be browsing your website! You can confirm that by looking at your traffic analytics.
The question is, how can you convert this traffic into sales to improve your bottom line? Geo targeting or geotargeting (regardless how you spell it) might be the key to that.
