Responsible for all internal developments, product roadmap, integrations, and certifications, among others. See the full Q&A below: ### **Pixalate: What services does E-Planning offer?** Sebastian Perez: [E-Planning](https://www.e-planning.net/) is one of the leading programmatic advertising companies.  We offer SSP and programmatic services developed with in-house technologies. We have integrated more than 13.500 tier 1 sites, 700 million unique users, more than 250B monthly impressions, and over 2500 apps from the US, EMEA, LATAM, APAC, and the rest of the world. We also have our proprietary Exchange which is integrated using server-to-server connections to other SSPs and direct demand from DSPs such as DV360, Mediamath, Centro, TTD, and our very own DSP. **Pixalate: How does E-Planning protect its customers from invalid traffic (IVT) and ad fraud?** **Sebastian Perez: **We are integrated with Pixalate using their Pre-bid and Post-bid solutions. Pre-bid solution allows us to detect and filter invalid traffic based on IP, user agent, or device ID before the auction takes place; this prevents sending bid requests that may have originated from bots or other non-human sources. On the other hand, the Post-Bid solution provides an analytic tool that helps us to identify and take action preemptively against more sophisticated invalid traffic. This year we got certified by the TAG Anti-Fraud program. It was a great experience and helped us big to improve our IVT filtering stack by adding new tools and applying good practices. ![Sebastian Perez e-planning protecting clients](https://www.pixalate.com/hs-fs/hubfs/Blog_Media/Blog%20photos/Sebastian%20Perez%20e-planning%20protecting%20clients.jpeg?width=646&name=Sebastian%20Perez%20e-planning%20protecting%20clients.jpeg) ### **Pixalate: What are the key steps to secure a transparent programmatic digital ad supply chain?** **Sebastian Perez: **First of all, having the ability to identify invalid traffic is the key to being able to filter it later. Applying a blacklist on the publishers is a great first step to excluding those sites and apps that are being flagged for having high IVT rates. Then applying filters based on user/device to filter those requests that may be originated from non-human sources. And finally, at the same time, we monitor all the traffic using an analytics tool, which is the only way to detect sophisticated invalid traffic (SIVT) that cannot be filtered only based on publishers and basic device information such as IP or Device ID.  ### **Pixalate: How does E-Planning provide access to granularly-targeted audiences without invalid traffic?** **Sebastian Perez: **Applying Pre-Bid and Post-Bid tools and integrating them into our system. There is no manual work on our end to apply a Pre-Bid blacklist, our platform just downloads it twice a day and updates all IPs, device IDs, sites, and apps list, and excludes them from any auction automatically. In consequence, we can filter out all the invalid traffic before the auction takes place. Then using Post-Bid tools help us to monitor sophisticated invalid traffic, get insights and work side by side with the publishers to remove the invalid traffic. ### **Pixalate: What are the key differences between platforms in delivering a quality inventory to advertisers?** **Sebastian Perez: **There is a part of the ad tech industry that is based on fraud, as happens with some other industries as well. Therefore it is so important to work only with partners that apply tools and good practices to filter IVT, check the publisher's reputation, and favor working with certified companies in anti-fraud programs, such as TAG Anti-Fraud. It is up to each party involved in the supply chain to apply best practices to ensure that advertisers' campaigns will be shown in a curated inventory, free of fraud. When advertisers run their campaigns in low-quality inventory, they are scammed twice. First, because they are probably paying for non-human traffic, and second because their metrics will be dissociated, and will be hard to understand how effective their campaigns are in reality. ### **Pixalate: Which trends, policies, and initiatives do you consider as possibly the most influential on the future of programmatic advertising?** **Sebastian Perez: **Advertisers will choose to work with partners that follow widely adopted standards by the industry such as ads.txt, app-ads.txt, sellers.json, and Supply Chain. Also, advertisers will privilege those who are certified in anti-fraud programs, which are being audited by third-party validators, who may check from an independent perspective that all good practices regarding IVT prevention are being applied. That is the only way they can ensure that their campaigns will be shown correctly to their target audiences. ### Search Blog Search ### Follow Pixalate ### Subscribe to our blog *By entering your email address and clicking Subscribe, you are agreeing to our [Terms of Use ](https://www.pixalate.com/terms)and [Privacy Policy.](https://www.pixalate.com/privacypolicy) Previous Story [← OFAC Russian Sanctions Tracker: List of Mobile Apps and Websites Registered to Sanctioned Entities (updated June 2022)](https://www.pixalate.com/blog/ofac-russian-sanctions-tracker) [** ](https://www.pixalate.com/blog) Next Story [Jalal Nasir at ATS London 2022: Children’s Privacy Risks in Mobile Advertising →](https://www.pixalate.com/blog/jalal-nasir-ats-london-2022-keynote) ## You May Also Like These Stories on Case Studies [![](https://www.pixalate.com/hubfs/Q%26A%20with%20Krush%20Media%20-%20cover.png) ](https://www.pixalate.com/blog/krush-media-qa) [Case Studies](https://www.pixalate.com/blog/topic/case-studies) ### [Q&A with Steven Slaughter, Head of Ad Ops & Yield at Krush Media, on managing a clean CTV and Mobile Ad Supply Chain](https://www.pixalate.com/blog/krush-media-qa) Jun 27, 2023 12:00:00 PM | 4 min read [![](https://www.pixalate.com/hubfs/Q%26A%20with%20Screencore%20-%20cover.png) ](https://www.pixalate.com/blog/screencore-qa) [Case Studies](https://www.pixalate.com/blog/topic/case-studies) ### [Q&A with Jess Okan, Co-founder and CEO of Screencore, on strategies for minimizing ad fraud in the connected TV ecosystem](https://www.pixalate.com/blog/screencore-qa) May 30, 2023 7:00:00 AM | 6 min read [![](https://www.pixalate.com/hubfs/Oleksandra%20Kazantseva.png) ](https://www.pixalate.com/blog/bizzclick-qa) [Case Studies](https://www.pixalate.com/blog/topic/case-studies) ### [Q&A with Oleksandra Kazantseva, Head of Programmatic at BizzClick, on transparency, trust, and security](https://www.pixalate.com/blog/bizzclick-qa) Apr 17, 2023 2:00:00 PM | 4 min read ** ### Subscribe to our blog *By entering your email address and clicking Subscribe, you are agreeing to our [Terms of Use ](https://www.pixalate.com/terms)and [Privacy Policy.](https://www.pixalate.com/privacypolicy) ![pixalate-logo-red-small](https://www.pixalate.com/hs-fs/hubfs/2018NewTemplate/pixalate-logo-red-small.png?width=208&name=pixalate-logo-red-small.png "pixalate-logo-red-small") ** By entering your email address and clicking Subscribe, you are agreeing to our [Terms of Use](https://www.pixalate.com/terms) and [Privacy Policy](https://www.pixalate.com/privacypolicy) Products [Analytics](https://www.pixalate.com/products/analytics) [Blocking](https://www.pixalate.com/products/blocking) [Media Rating Terminal](https://www.pixalate.com/products/mrt) [Publisher Trust Indexes](https://www.pixalate.com/rankings/?group=app&reportId=publisherTrustIndex) [Seller Trust Indexes](https://www.pixalate.com/rankings/?group=app&reportId=publisherTrustIndex) [IoT Device Rankings](https://www.pixalate.com/rankings/?group=app&reportId=iotDeviceReach) Resources [Blog](https://blog.pixalate.com/) [Press](https://www.pixalate.com/press) [Careers](https://www.pixalate.com/jobs) [Team](https://info.pixalate.com/pixalate-leadership-team) Contact Email [** sales@pixalate.com ](mailto:sales@pixalate.com) [** privacy@pixalate.com ](mailto:privacy@pixalate.com) US: [** +1 888 749 2528 ](tel:+1%20888%20749%202528) EU: [** +44 (0)800 011 2050 ](tel:+44%20(0)800%20011%202050) Slack: [Join ATSAPI Slack Channel ](https://atsapi-pixalate.slack.com/join/shared_invite/zt-10dtow5cj-OEtlNr5yzJkrZMQUqcEEow#/shared-invite/email) Offices Global Offices US 1775 Greensboro Station Place, Suite 425, McLean, VA 22102 UK 20 North Audley Street London, W1K 6WE, United Kingdom EU 10 Earlsfort Terrace Dublin 2, D02 T380, Ireland Singapore 10 Anson Road, #22-02 International Plaza, Singapore 079903 [![facebook](https://www.pixalate.com/hubfs/footer/icons/facebook.png) ](https://www.facebook.com/pixalate) [![x](https://www.pixalate.com/hubfs/footer/icons/twitter-x.png) ](https://twitter.com/pixalateinc) [![linkedin](https://www.pixalate.com/hubfs/footer/icons/linkedin.png) ](https://www.linkedin.com/company/pixalate) ![wechat](https://www.pixalate.com/hubfs/footer/icons/wechat.png) [![slack](https://www.pixalate.com/hubfs/footer/icons/slack.png) ](https://atsapi-pixalate.slack.com/join/shared_invite/zt-10dtow5cj-OEtlNr5yzJkrZMQUqcEEow#/shared-invite/email) [Terms of Use](https://www.pixalate.com/terms) [Privacy Policy](https://www.pixalate.com/privacypolicy) [GDPR Compliance](https://www.pixalate.com/gdpr) Disclaimer Copyright © 2025 Pixalate [Back to top **](https://www.pixalate.com/blog/eplanning-qa#) # Disclaimer Disclaimer: The content of this page reflects Pixalate’s opinions with respect to the factors that Pixalate believes can be useful to the digital media industry.

Per the MRC, “'Fraud' is not intended to represent fraud as defined in various laws, statutes and ordinances or as conventionally used in U.S. Court or other legal proceedings, but rather a custom definition strictly for advertising measurement purposes. Also per the MRC, “‘Invalid Traffic’ is defined generally as traffic that does not meet certain ad serving quality or completeness criteria, or otherwise does not represent legitimate ad traffic that should be included in measurement counts. Among the reasons why ad traffic may be deemed invalid is it is a result of non-human traffic (spiders, bots, etc.), or activity designed to produce fraudulent traffic.” ** ** *By clicking Download and entering your email address, you are agreeing to our [Terms of Use](https://www.pixalate.com/terms) and have read and acknowledge our [Privacy Policy](https://www.pixalate.com/hubfs/2024-08-20_Pixalate_Privacy_Policy.pdf). *Copyright © 2025 Pixalate** * * * * * * * * * * * * * * * * * * * * * * * * * * * * × ## Subscribe to the Pixalate Blog The first step in ad fraud prevention.
